A linear regression is worth a maximum of 5 points; a multiple regression is worth a maximum of 10 points and both are worth 13 points. You must analyze the regression(s) that you do. The better job that you do, for instance, checking the residuals and for multicollinearity, the more points you get. If you choose to do a linear regression then you must compare the list price to the square footage. You are to project out the listing price of a home that has 2750 square feet. If you choose to do the multiple regression then you must compare the list price to all the varables in the data file, square footage, number of bedroom, number of bathrooms, number of cars in the garage, and the age. You must project out the cost of a house with 2650 square feet; that is 10 years old, with 3 bed and 3 bathrooms with a garage that sleeps 3 cars.

Paper

...FORECASTING FINANCIAL STATEMENTS:  PROFORMA ANALYSIS Roger Clarke and Grant McQueen August 2001 ABSTRACT This teaching note explains why and how managers project financial statements into the future. The note is designed for an introduction to corporate finance class. The note prepares students for either a case such as Clarkson Lumber or a real-word project in which proforma statements are needed. This note explains how to build a proforma balance sheet and intentionally does not include a complete proforma income statement so that the students will have to demonstrate some ingenuity when doing the follow-on case or project. The note is a nice supplement to both the advance and remedial corporate finance text books. The more advanced books (e.g., Ross, Westerfield, and Jaffe) typically give short shrift to the topic of forecasting and the more remedial text books (e.g., Block and Hirt) typically build the forecasted statements presupposing the manager knows production projections (e.g. the type, number, and price of units to be bought, produced, and sold). Roger Clark is with Analytic-TSA Global Asset Management and an Adjunct Professor in the Marriott School at Brigham Young University. Grant McQueen is the William Edwards Professor of Finance in the Marriott School at Brigham Young University. The authors thank colleges at BYU and ASU and the research assistance and students for their contributions. Send correspondence to Grant McQueen, 671...

Littlefield

...Background In early January 2006, Littlefield Technologies (LT) opened its first and only factory to produce its newly developed Digital Satellite System (DSS) receivers. Littlefield Technologies mainly sells to retailers and small manufacturers using the DSS’s in more complex products. Littlefield Technologies charges a premium and competes by promising to ship a receiver within 24 hours of receiving the order, or the customer will receive a rebate based on the delay. The product lifetime of many high-tech electronic products is short, and the DSS receiver is no exception. LT managers have decided that, after 268 days of operation, the plant will cease producing the DSS receiver, retool the factory, and sell any remaining inventories. As this is a short life-cycle product, managers expect that demand during the 268 day period will grow as customers discover the product, eventually level out, and then decline. In the initial months, demand is expected to grow at a roughly linear rate. Demand is then expected to stabilize. Eventually, demand should begin to decline at a roughly linear rate. Although orders arrive randomly to LT, management expects that, on average, demand will follow the trends outlined above. Management’s main concern is managing the capacity of the factory in response to the complex demand pattern. Delays resulting from insufficient capacity undermine LT’s promised lead times and ultimately force LT to turn away orders. In particular, if an order’s...

Biostatistics

...PHEB 609: Categorical Data Analysis Homework 6 1. A study used logistic regression to determine characteristics associated with Y = whether a cancer patient achieved remission (1 = yes). The most important explanatory variable was a labeling index (LI) that measures proliferative activity of cells after a patient receives an injection of tritiated thymidine. It represents the percentage of cells that are “labeled”. Table 7.1 shows the grouped data. Table 6.1 Data for Problem 1 on Cancer Remission a. Fit a logistic regression model to the data using LI to predict π = P(Y = 1). State the prediction equation. Logit π (X) = -3.7714 + 0.1448 (LI) b. Use the model fit equation to estimate by hand the probability of remission when LI=8 π (8) = e -3.771 +0.1449 (8) 1 + e -3.771 + 0.1449 (8) = 0.068 c. Obtain the value of LI for which the predicted probability of remission is 0.5 . π (X) = e -3.771 +0.1449 (X) 1 + e -3.771 + 0.1449 (X) = 0.5 e -3.771 + 0.1448 (LI) = 0.5[ 1 + e -3.771 + 0.1448 (LI)] e -3.771 + 0.1448 (LI) = 0.5 + 0.5 e -3.771 + 0.1448 (LI) e -3.771 + 0.1448 (LI) - 0.5 e -3.771 + 0.1448 (LI) 0.5 e -3.771 + 0.1448 (LI) = 0.5 e -3.771 + 0.1448 (LI) = 1 -3.7714 + 0.1448 (LI) = In (1) 0.1448 (LI) = 3.7714 LI = 3.7714/0.1448 =26. d.

Determinants of Ar-Rahnu Profit

...few years, a pawn broking has taken place in our country. It has been started since the 15th century which was introduced by the Chinese traders during the Malacca Sultanate. Then, it continued to expand after the discovery of tin mining in Larut in the 19 century. Pawn broking can be traced back to at least 3,000 years in ancient China. It also has been found in the earliest written histories of Greek and Roman civilizations. According to the Islamic Financial Services Board (IFSB), the Ar- Rahnu scheme can demonstrate its roles as a viable microcredit product of the financial institution in meeting the different customer requirements. Firstly, it represents a credit channel to those who want to use Ar-Rahnu scheme to obtain financial resources to meet their daily financial requirements; and secondly, it can be a credit channel to those who requires temporary working capital, particularly for small business. The objective of Ar-Rahnu is to create an alternative financing channel to the conventional pawn broking, that is not only more transparent but it also more compliant with Shari’ah principles. Ar-Rahnu is a form of microcredit product the borrower places their valuable assets such as gold or jewellery as collateral for the financing. In conventional pawn broking, the interest is charge based on the loan. On the other hand, Ar-Rahnu has no interest but it charges on safekeeping service. 1.2 BACKGROUND OF THE ORGANIZATION 1.3.1 BANK RAKYAT Bank...

Factors Affecting Retailers

...framework was designed based on the literature and hence two hypotheses were formulated. The samples were selected by Proportionate Stratified Sampling method. The data were collected by distributing 10 items questionnaires to 50 retailers under different categories in Dhaka. The questionnaire was developed on the basis of exploratory research which were used to measure retailers attitude. Data collected were sorted out and keyed in into SPSS and were analyzed using descriptive statistics to answer the research question. Using the Factor analysis we have extracted four factors and named those factors as Manufacturer’s Production Standard, Managerial Efficiency, Promotional Capability and Customer Solution Capability. The result of the Multiple Regression analysis showed that there is a significant relationship between retailers’ attitude (dependent variable) and the factors determined in the factor analysis (independent variables). Together the independent variables explained 67.9% of the variance of the dependable variables whereas the remaining 32.1% was due to unidentified variables. Therefore the results of the study definitely play a vital role and leave an ever lasting impact to be used in decision making by retailers and the entire company as a whole....

...financial institution might be fraught with unmanageable risks for the purpose of maximizing its potential return. In such a situation, the banking financial institutions might find itself in serious financial distress instead of improving its financial health. Consequently, not only the depositors but also the general shareholders will be deprived of their money from the bank. The deterioration of loan quality will also affect the intermediation efficiency of the financial institutions and thus the economic growth process of the country. This establishes the fact that banks should provide increasing emphasis on various analytical tools and techniques for screening proposals and loan decision taking. Credit Worthiness Analysis is one of the most important activities before sanctioning any credit to a new borrower as well as existing borrower to avoid any default risk and for improving the operational efficiency of nationalized and private sector commercial banks. 1.2 Rational of the study: The principal function of the bank is to lend. Lending comprises a very large portion of a bank’s total activities. Sound lending practice therefore, is very important for profitability and success of a bank. Like other financial intermediary, commercial banks also intermediate between the savers and borrower to mobilize the financial surplus of the savers and allocate these savings to the creditworthy borrowers of different sectors of the economy.

...the next few years. In the last four quarters, we have successfully launched the six customer tailored products for three regions. For each distribution channel, we chose specific packages to meet our distributors’ requirement on packaging. By investing in reduction of setup time, we were able to change our production faster in order to meet changes in customers’ preference and market trend. We also invested in production equipment thereby reducing batch size to support our LEAN manufacturing philosophy. In doing so, we successfully attained production flexibility while incurred only a small amount of extra interest expense due to the early investment in long-term equities that spread out investment cost during the whole machine life. Also, our credit rating was consistently the best in the industry, proving that we are headed in the right direction. With the highest AAA credit rating, we had an advantage of taking banks loans at a low cost, which, in turn, further lowered our total cost.  For next year, as we continue to price specific products more carefully, while keeping the average market prices in mind, it will allow us to launch more region specific products and continue to innovate and improve our products which will set higher standards of success and expect higher customer...
