Regression Analysis - Speech or Presentation Example In essence, it allows for evaluation of the fixed and random effects models in non-linear modeling frameworks and simply assumes parameter and variable non-linearity. Assumption 2: Expected value of error is zero This assumption presumes that the error component will return a zero mean meaning that the observed mean will not be systematically distorted away from the true value by the error (and this contrasts with a systematic bias effect which would distort the observed mean away from its true value) (Good & Hardin, 2009). Assumption 3: Autocorrelation Amongst the assumptions often made in regression analysis is that error terms not dependent on each other or rather non-correlated. This is however not always the case. When this assumption is violated, despite the fact that the regression model is still usable, in prediction value, its usefulness is largely diminished. This study considering the relationship between the variables seeks to assume its presence and hence proof that the model’s usability is largely diminished. The estimated regression parameters, a, b1, b2, . . . ,bk, are left as unbiased estimators of the respective real values, A, B1, B2, . . ,Bk, and hence the model remains appropriate for establishment of point estimates of A, B, and others., and it can be used in prediction of values of Y for X value sets (Good & Hardin, 2009) (Good & Hardin, 2009). Autocorrelation is often a product of errors correlation. It broadens the scope of thinking to look at different observations which result from varying distributions which are non-explanatory. Assumption 4: Heteroskadascity Sphericality assumption often implies that there exists homoskedasticity of errors, and that variance is constant across cases. Violation of this offers heteroskedasticity whereby the predictive model does particularly poor in some set of circumstances. Take for instance in this case where there is a possibility that unemployment or gas prices across countries may be reli able but there is lesser proof to believe in the data relating to the same obtained from other countries. Such a case would give rise to increased random variation, and hence huge mean error variances, in the respective countries. In general, Heteroskedasticity occurs in instances where the homoskedasticity assumption is violated, giving rise to Assumption 5: Multi-collinearity assumption Whenever there exists moderate to high intercorrelation amongst predictor variables, multi-collinearity is believed to arise. Typically, multi-collinearity presents a real research problem when multiple regressions are used. These include its severe limiting of R’s size given that predictors follow a variance as much the same as that of y, creating a difficulty in determination of the worth of a predictor due confounding of the effects as a result of correlation between them, and an increment in regression coefficient variants (Good & Hardin, 2009). In this case’s, a number of variabl es are considered in the model including gas price, excluding food prices, unemployment, and personal expenditure which was removed due to its high correlation to the other variables. However, even with the inclusion of the other variables, it is still believed that the other variables have some slight correlation to each other. For instance, food services are likely to be impacted on by gas prices and the same is true for unemployment rates. Conclusion Understanding relationship

An Evaluation of CRM Strategy at Ping An Life Insurance, China Dissertation

An Evaluation of CRM Strategy at Ping An Life Insurance, China - Dissertation Example Ping An has been recognized and awarded for its customer relationship management approach but an evaluation of data suggests the adoption and implementation of CRM is not professionally and strategically adequate. Emphasis on salesmen appears to a hindrance to growth and accountability is lacking at Ping An. After evaluation of the available data, recommendations have been made on how CRM can be effectively implemented at Ping An Life Insurance. China Insurance industry Life insurance business in China is huge and intensely competitive, according to Binder, Bowers and Yung (2004) of The McKinsey Quarterly. China is now the world’s fastest growing major life insurance market. The drivers of growth in the sector include 40 percent household savings rate, limited and deteriorating public-pension and health schemes that have heightened the demand for personal retirement savings and protection tools. Consumers sought investment options but the choice was limited. No attractive mutual funds offers are available and consumers cannot invest overseas. Bank yields are very low compared to typical savings policy. This helped to stimulate growth in the insurance sector in 1990 when foreign insurance companies were allowed to enter China either in joint venture with 50:50 partnership or with a maximum of 25 percent ownership. However, within 15 years more than 90 percent of insurance sector is with three domestic insurers – China Life Insurance, Pi ng An Insurance and China Pacific Life Insurance. The insurance industry is among the fastest growing industries in China and is the core business of the Ping An Group (Annual Report, 2012). However, the Chinese insurance business is in transition and hence has to adjust for sustainable and healthy growth (Market Review, 2012). This is critical since China’s economy is growing and personal wealth is expanding and hence sustainable growth becomes essential. Besides, competition is setting in as foreign insurers’ operational areas have expanded, which means they can operate in geographical regions they were earlier barred from. Besides, despite the three domestic insurers having large number of agents, the productivity on an average is less than one-fourth of Hong Kong agents. It has also been found by Binder, Bowers and Yung (2004) that these agents give misleading information and poor customer service. Such issues would allow the foreign insurers to increase their mark et share of the affluent and mass-affluent segment. 1.2 Customer

Monopolies in Todays Market Essay Example | Topics and Well Written Essays - 2000 words

Monopolies in Todays Market - Essay Example Atimes, monopolies exist as a result of government backings in which case the monopolies provide goods, products or services which the government considers essential to the well being of the people. The absence of supply curve in the monopolized market causes inefficient allocation of society's resources. Therefore there is that tendency for a monopolist to charge high prices and probably making higher profits compared with firms in perfect competition. The objective of this paper is to unravel the role of monopolies in today's market and the implications of technology and systems on the monopolies. The rest of this paper examines different types of monopoly, its revenue, monopoly and price discriminations, and implications of technology and systems. (a) Pure Monopoly: This is a type of monopoly that exists in a particular region or city in which its products have no close substitutes. This makes it possible for the monopolist to charge extra prices because their products are necessities. (b) Natural Monopoly: A monopoly that exists because of economies of scale it enjoys in which large scale production brings lower average cost. Even though a competitor arises in the industry lower prices the monopolist would charge is capable of sending the competitor off the market. (c) Efficiency Monopoly: When government does not legalize monopoly, a monopoly may exist largely due to its ability to satisfy the customers in which case competition is inadvertently rule out. (d) Legal Monopoly: This form of monopoly has government backing such that laws are enacted to simply rule out competition. Wikipedia says "when such a monopoly is granted to a private party, it is a government granted monopoly; when it is operated by government itself, it is government monopoly or state monopoly". Monopoly Revenue Basically, a monopolist faces downward sloping demand curve which is also the firm's average revenue curve. As the monopolist sells a single price for its products, average revenue per product is the same as the price. For the monopolist to increase its sales it charges lower unit price for its products. At price P1 the monopolist only manages to sell Q1 quantity of the product; in order to increase its sales it reduces the price from P1 to P2 and as such sales is increased from Q1 to Q2 which he now gains in figure 1 below. Given the above scenario, the differential of the total revenue in relation to quantity gives marginal revenue which shows that the additional revenue large enough to offset the reduction in price. Figure 1: Showing Monopolist's gain brought about by price reduction. However, the monopolist maximizes profit where marginal revenue equals marginal cost. The reason is the since marginal cost is always greater than zero the monopolist will operate at profit because marginal revenue will be positive and where demand is elastic. If the monopolist stops production where marginal cost is less than marginal revenue, he will be leaving his profit untapped while quantity in which marginal revenue is greater than marginal cost the firm will be operating at losses. Profit maximizing price is determined by drawing a line where marginal co

Revenue Cycle Improvement in Healthcare Case Study

Revenue Cycle Improvement in Healthcare - Case Study Example Therefore, this manual is a guide that gives an alternative approach to the management of revenue cycle components. The manual includes the best strategies for managing patients at five stages in the hospitals. For instance, the guide will consider best practices for patient access, charge capture, utilization review, and billing and payment accuracy. This approach puts the patient at the focal point of the process of revenue collection (RHIP 2014). The approach also encourages the hospital staff concerned with the process to build better approaches with the patients. The third element of the approach is an established communication with the patients either in written or orally. The creation of a positive experience for patients within the revenue cycle forms a critical step towards the success of the program. As such, the hospitals should train their staff to meet the customer satisfaction points. For example, the workers should answer questions related to the healthcare marketplace. They should also articulate coverage options and discuss the options available for payments. Lastly, the hospital staff should know when or when not to escalate. Therefore, the hospitals should adopt methods that will make the customer aware of all the billing processes at the hospital. The existence of a centralized system gives the patients a one-stop chance for a single contact centre. It also minimizes the possibilities for errors and missing data. There is an understanding that deficiencies in data systems could result in backlogs clear a patient’s financial records. Best practice hospitals should engage in a number of methods that will realize the efficiency of the revenue cycle. First, the hospitals should have a centralized scheduling for receiving patients. Such a step will help the hospitals to have a precise projection of the types of patients that they receive and the details of their payment abilities.

Advanced Financial Reporting - Essay Example Another way of achieving growth is through Merger and Acquisition (abbreviated as M&A). The former is also known is organic growth where the firm uses its own resources (retained earnings, reserves and surplus, or equity capital) for financing growth. The later is also known as inorganic growth where the acquirer firm buys the assets and liabilities of the target(s) as on a given date (Sherman, 2010, p.1). Thus, M&A are external growth strategy that gains popularity mainly due to globalization. It has become an important an important way for firms to expand their product portfolios and gaining new markets. M&A also helps the firm’s to acquire knowledge, latest technology and improved management capabilities. In addition, M&A has been found to be extremely successful for specific sectors like pharmaceuticals where extensive Research & Developments are required. R&D does not only require huge capital investment but also requires knowledge in relevant areas so that the target pro duct remains competent on global scale (Kumar and Yadav, 2005, pp.51-63). The main motive for any M&A is to experience a synergy in existing operations as well as profitability of the firms. However, it is also important to note that not all M&A have been successful in the past and thus some failed to maximise values leading to huge capital losses (Frensch, 2007, pp.48-49).

CCTV Cameras - Criminal Investigation Essay Example | Topics and Well Written Essays - 3000 words

CCTV Cameras - Criminal Investigation - Essay Example This paper shall discuss CCTVs and their general impact, as well as their impact on criminal investigation. An initial discussion on the use of CCTVs will first be discussed, followed by the application and implications in the use of these cameras. The use of these CCTVs for criminal investigation will then be presented, alongside a discussion on whether or not these CCTVs are advantageous or disadvantageous. Concluding remarks shall summarize and end this article. This paper is being carried out in order to establish a clear understanding of CCTVs and to add to future knowledge regarding CCTVs and their general applicability in criminal investigation. In 1942 Germany, the first CCTV system, which was designed by Walter Bruch, was setup by Siemens AG as a means of observing V-2 rockets (Dornberger, 1954). In the United States, CCTVs were first used in 1973 at the Times Square in New York. They were first installed as a crime deterrent; however, crimes committed in the area did not drop by much even with the presence of such cameras (Yesil, 2006). In a few years time however, the use of these cameras gradually expanded to other parts of the country, most especially the public spaces (Roberts, 2010). These cameras were also considered a cheaper alternative in crime prevention, discarding the need to increase police presence in public areas (Roberts, 2010). Businesses also realized the benefit of these cameras in terms of improved security. This technology improved throughout the years, especially with the advent of digital technology which allowed for simultaneous recording as well as time lapse or motion-only recording (Roberts, 20 10). More cameras have also been installed in schools, parks, parking lots, malls, and since the 2001 terrorist attacks, more surveillance videos have been secured in various parts of the country (Yesil,
