Table of Contents Introduction Scatter diagram Correlation coefficient Relationship between the variable Regression Results Evaluation of regression model R-square value Regression equation Prediction Introduction Regression analysis is a statistical tool that is used to develop and approximate linear relationships among various variables. Regression analysis formulates an association between a number of variables. When coming up with the model, it is necessary to separate between dependent and independent variables. Regression models are used to predict trends of future variables. The paper carries out a simple regression analysis between the price of houses and the area of houses. Scatter diagram A scatter diagram is a graph that plots two related variables on a Cartesian plane. The independent variable is plotted on the x – axis while the dependent variable is on the y – axis. In this case, the price of houses (in thousands) is plotted on the y – axis while the area of houses (in square feet) is plotted on the x – axis. Scatter diagram tries to establish if there exists a linear relationship between two variables plotted on the diagram. This can be observed by looking at the trend of the scatter plots. Points on the scatter diagram tend to slope upwards. It is an indication of a positive linear relationship between the prices of houses and the area of houses in square feet. This implies that as the area of houses increases, the price also increases. Few points fall on the regression line drawn in the scatter diagram. There are several that fall outside the regression line. Further, there is a lot of concentration around 2000 square feet. This concentration affects the linearity of the model. This can be an indication of a weak regression line. A strong regression line is indicated by concentration of points along the regression line. Correlation coefficient The correlation coefficient is 0.6364. The coefficient is positive and greater than five. This implies that there is a positive linear relationship between price of houses and the area of a house. That is, as the area of the houses increase, the price of a house also increases. Get your 100% original paper on any topic done in as little as 3 hours Learn More Relationship between the variable There are a number of factors that affect the price of houses. A direct factor is the area of the house. However, that is not the only factor that affects the price of houses. Examples of these other factors include the location of the house and proximity to various social amenities. Only one factor will be used in this regression analysis thus yielding a simple regression. The dependent variable is the price of houses while the independent variable is the area of the houses (in square feet). The regression line will attempt to establish a linear relationship between price of houses and the area of the houses. A sample of twenty houses is used to estimate the regression equation. The regression line will take the form Y = b0 b1X Y = Prices (in thousands) X = Area (square feet) The theoretical expectations are b0 can take any value and b1 > 0.

Get your first paper with 15% OFF Learn More Regression Results The result of regression for each independent variable is shown in the table below. Variable Coefficients of the variable a0 Y – intercept 160.3961978 a1 Coefficient of area (in square feet) 0.066744981 From the above table, the regression equation can be written as Y = 160.40 0.0667X. The intercept value of 160.39619 is not dependent on the area of the house but on other factors such as the location of the house. The value captures all other factors that were not included when modeling the regression line. The coefficient value of 0.066744 implies that as the area (square feet) of the house increases by one unit, the price of the house will increase by 0.0667 units. The positive value of the coefficient implies a positive relationship between the price and area of houses. Evaluation of regression model Evaluation of the regression model can be done by testing the statistical significance of the variables. Testing statistical significance shows whether the explanatory variable is a significant determinant of the price of houses. A t – test will be used since the sample size is small. A two tailed t- test is carried out at 95% level of confidence. Null hypothesis: Ho: bi = 0 Alternative hypothesis: Ho: bi ≠ 0 The table below summarizes the results of the t – tests.

We can help you for only \$16.05 \$11/page Learn More Variable t – values computed t at α 0.05 Decision a0 Intercept 3.078114047 1.9432 Reject X1 Area (in square feet) 3.500704245 1.9432 Reject The null hypothesis implies that the variables are not significant determinants of demand. The alternative hypothesis implies that variables are significant determinant of demand. From the table above, the values of t – calculated are greater than the values of t – tabulated. Therefore, the null hypothesis will be rejected and this implies that the area (in square feet) is a significant determinant of the explanatory variable. Thus, area (in square feet) is statistically significant at the 95% level of significance. The value of the intercept is not relevant when testing the significance of the regression variables. Since the explanatory variable is statistically significant, it implies that the regression line can be used for prediction. The regression model shows that the slope is not strong enough though the regression coefficient shows a positive relationship between the prices and the area of houses. Thus, the model can be used in predicting the prices since as the price increases there is a corresponding increase in areas of houses. More variables should be added to the regression line so as improve on the regression equation. R-square value Coefficient of determination estimates the amount of variations of the dependent variable explained by the independent variables. A high coefficient of determination implies that the explanatory variables adequately explain variations the demand function. A low value of coefficient of determination implies that the explanatory variables do not explain the variations in price of houses adequately. For this regression, the value of R2 is 40.5%. This implies that the area (in square feet) explains only 40.5% of the variation in price of houses. It is an indication of a weak explanatory variable. Also, the value of adjusted R2 is low at 37.20%. The value of R2 can be improved on by adding more variables in the regression model. Regression equation The regression line is Y = 160.39619 0.06674X. Prediction From the regression line, prices of houses can be estimated. For instance, the regression line can be used to estimate the price of a house whose size is 3000 square feet. The computation of the price is shown below. Regression equation Y = 160.39619 0.06674 X The house price (\$ 1, 000) = (0.0667 × House area (square feet)) 160.3962 = (0.0667 × 3, 000) 160.396 = 360.63114 = 360.63114 × 1, 000 = \$360,631.14 A house of size 3,000 square feet house will cost \$360,631.14.

Table of Contents Introduction Positive Externalities Types of Profit Externalities Conclusion References Introduction Externalities are the impact of economic entities participating in a particular transaction on third parties who are not involved in the deal. These are factors that are not taken into account when determining the gross national product but have an influence on people’s welfare. In order to analyze the effect of this phenomenon in more detail and to assess profit externalities, it is required to consider the classification of these economic components and what they are. Such a description will give an opportunity to assess the degree of their impact on the economic environment and help to determine if profit externalities can be useful for business. Positive Externalities Positive externalities are the beneficial effects of economic entities participating in the transaction of third parties. They are the utility that is not reflected in prices. According to Dragone, Lambertini, and Palestini (2014), with a positive external effect, marginal social utility exceeds marginal individual utility. Due to the fact that third-party external beneficiaries do not take part in the conclusion and execution of transactions with this commodity, their profits are not taken into account when concluding such transactions, and equilibrium prices and quantity established in the market differ from those that would be received in this manner. The result of positive external effects is the inadequate production and understatement of a certain product’s price, which leads to a decrease in the efficiency of the economy (Agafonow, 2014). Therefore, in order to ensure an effective output volume, a mechanism is necessary through which third parties, using the external effect, would contribute to its production and consumption. At the same time, one part of the contribution would be aimed at reducing the price paid by consumers in order to stimulate the growth of their consumption. The other part would be used to compensate for any increase in marginal costs in order to encourage producers to increase output. Types of Profit Externalities Profit externalities can be assessed from the point of view of their impact on economic activities by categorizing them. According to these groups, certain utility functions are performed, which should be taken into account when drawing up transactions. All the categories are relevant and may be applied to relevant financial activities. Based on specific principles of utility, market participants regard the importance of these externalities differently. The marginal individual utility of goods is the utility received by a person buying the additional unit of a specific product (Möhlmeier, Rusinowska,

Mini Case: Capstone Case: New Century Wellness GroupNew Century Wellness Group offers a holistic approach to healthcare with an emphasis on preventive medicine as well as traditional medical care. In your role as an IT consultant, you will help New Century develop a new information system.BackgroundYou began the systems analysis phase by conducting interviews, reviewing existing reports, and observing office operations. (Your instructor may provide you with a sample set of interview summaries.)The New Century medical team performs services and medical procedures, which are coded according to the American Medical Association’s Current Procedure Terminology (CPT). CPT codes consist of five numeric digits and a two-digit suffix, and most insurance payers require the codes to be included with billing information.The new system must be able to handle the new ICD-10 procedure coding system, which will be required by the Centers for Medicare & Medicaid Services (CMS) beginning October 1, 2014. ICD-10 codes consist of seven alphanumeric characters, which can be electronically transmitted and received. New Century’s information system must interface with 25 California health insurance providers. The new system represents an opportunity for significant cost saving for New Century, and more convenience for patients, who will be able to go online to update medical information, schedule appointments, and request medical records.During your fact-finding, you learned that the clinic requires various reports, as follows:Daily appointment list for each provider. The list shows all scheduled appointment times, patient names, and services to be performed, including the procedure code and description.Daily report call list, which shows the patients who are to be reminded of their next day’s appointments. The call list includes the patient name, telephone number, appointment time, and provider name.Weekly provider report that lists each of the providers and the weekly charges generated, plus a month-to-date (MTD) and a year-to-date (YTD) summary as well as profit distribution data for the partners.Monthly patient statement, which includes the statement date, head of household name and address, previous month’s balance, total household charges MTD, total payments MTD, and the current balance. The bottom section of the statement shows activity for the month in date order. For each service performed, a line shows the patient’s name, the service date, the procedure code and description, and the charge. The statement also shows the date and amount of all payments and insurance claims. When an insurance payment is received, the source and amount are noted on the form. If the claim is denied or only partially paid, a code is used to explain the reason. A running balance appears at the far right of each activity line.Weekly Insurance Company Report.Monthly Claim Status Summary.In addition to these reports, the office staff would like automated e-mail and text messaging capability for sending reminders to patients when it is time to schedule an appointment. Data also needs to be maintained on employers who participate in employee wellness programs. This information can be used for marketing purposes throughout the year. Finally, the new system needs to track employee schedules, attendance, vacation time, and paid time off.Now you are ready to organize the facts and prepare a system requirements document that represents a logical model of the proposed system. Your tools will include DFDs, a data dictionary, and process descriptions.Tasks(30 pts) Prepare a context diagram for New Century’s information system. (Follow the textbook standards for diagram. Please see Fig 5-12)(45 pts) Prepare a diagram 0 DFD for New Century (See Fig 5-13). Be sure to show numbered processes for handling appointment processing, payment and insurance processing, report processing, and records maintenance. Also, prepare lower-level DFDs for two numbered process. (Follow the textbook standards for diagram. Please see Fig 5-14)(25 pts) Prepare a list of data stores and data flows needed for the system. Under each data store, list the data elements required. (Please read section 5.6 carefully not to miss any items. Please note that you don’t need to use any special software to create this list)
