**Question**

Review the Regression Help document found in the Week 6 Discussion intro area, as well as the explanation in your course text (see textbook beginning page 563). Estimate the revenue, receivables, inventory, or payables of one your portfolio companies selected in the Week 4 discussion. Find their financial data at http://finance.yahoo.com/ calculate a projection for the next 12 months, and then show your source data and calculations to your colleagues. (believe this was already asked would be willing to pay the tutor joseph.wamwere for the work already done). Thanks!;Solution for Discussion 2;Managers must determine expected costs, expenditures, and revenues associated with a company's assets in;order to then make decisions about short and long-term uses of capital. Accurate forecasting leads to maximized;returns.;Using regression (see textbook beginning page 563), estimate the revenue, receivables, inventory, or payables of;one your portfolio companies selected in the Week 4 discussion. Find their financial data at;http://finance.yahoo.com/ calculate a projection for the next 12 months, and then show your source data and;calculations to your colleagues. The initial posting is due before Day 3.;Regression trends the relationship between variables. The dependent variable is identified as the Y variable and;the independent is the X variable. For the purposes of this class we will only deal with simple linear regression;(the relationship between two variables - one y and one x - or one dependent and one independent). Dependent;variables are the data item we which to predict. Independent variables are the predictor data. They help us in;determining the value of the dependent variable.;Below is and example using the textbook material on regression on p564 and additional example using Microsoft.;To begin we need to make sure your Excel package has all the add-in packages loaded and ready to use. How to;perform this software loading step depends on which version of Excel you have (2007 or pre-2007). The;instructions below are general in nature to help with both Excel software programs.;Step 1. See if your Excel program has the add-in called Analysis Tool Pak loaded;a. If so, you will see a menu option called Data Analysis under the Data menu;b. If not, click on your help file and search for Data Analysis Tool Pak to determine how to load this.;Step 2: Click on Data Analysis and select Regression.;Step 3: Answer the questiions and fill in the blanks, Excel does the rest.;To complete regression, you need to determine the relationship between a couple of variable in your company.;Start by getting five years of ending balances for each of the balance sheet items above from your company.;Hint: you may have to go into the SEC Form 10k or an annual report on the company website to get this.;Example from our text on page 564;X Y Excel Regression output using the X/Y variables.;Year Revenues Inventory Receivables SUMMARY OUTPUT;2001 2058 387 268;2002 2534 398 297 Regression Statistics;2003 2472 409 304 Multiple R 0.710962602;2004 2850 415 315 R Square 0.505467822;2005 3000 615 375 Adjusted R Square 0.340623762;Standard Error 77.74724334;Observations 5;ANOVA;df SS MS F Significance F;Regression 1 18534.89846 18534.9 3.066339 0.178228;Residual 3 18133.90154 6044.634;Total 4 36668.8;Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Upper 95.0%;Intercept -35.70298444 276.5952591 -0.12908 0.905462 -915.953 844.5466 -915.953 844.5466;Revenues 0.186039563 0.106241747 1.751097 0.178228 -0.15207 0.524148 -0.15207 0.524148;Note the coefficient for Revenues of.186 and the Intercept of$-35.70.
