Financial analysts who make forecasts of stockprices are categorized as either "buy-side" analysts or "sell-side"analysts. Refer to the Financial Analysts Journal (July/August2008) comparison of earnings forecasts of buy-side and sell-sideanalysts, Exercise 2.86 (p. 87). The mean and standarddeviation of forecast errors for both types of analysts arereproduced in the table. Assume that the distribution of forecasterrors are approximately normally distributed.a. Find the probability that a buy-side analyst has aforecast error of +2.00 or higher.b. Find the probability that a sell-side analyst has a forecasterror of +2.00 or higher.

The problem below looks at forecasting methodologies to determine which forecasting model results in the most accurate forecasts. Accuracy is determined by the lowest mean absolute deviation. Emergency calls to the 911 system of York County for the past 24 weeks are shown below. Accurate forecasts are needed to determine the number of operators needed to staff the station. Week # of Calls 1 50 2 35 3 25 4 40 5 45 6 35 7 20 8 30 9 35 10 20 11 15 12 40 13 55 14 35 15 25 16 55 17 55 18 40 19 35 20 60 21 75 22 50 23 40 24 65 SIMPLE LINEAR REGRESSION Use all of the data, weeks 1 - 24, to calculate the regression equation for this data. Use the weeks (1-24) as the independent variable (x) and number of calls as the dependent variable (y). Once you have the equation, forecast weeks 4 through 24 (enter 4, 5, 6, etc. as the x…
