Homework Answers
We have given the 10 latest forecasting percentage errors are 10%, 5%, 7%, 8%, 5%, -1%, 4%, 6%, 4%, 6%,
From this it can easily observed that error % is positive so it indicates that -
b. The current forecasting model overestimates the actual value

Assume that the variable Y is actually determined by the following equation Y; = Bo + B1X1,i+ B2X2,i + Uj additionally assume that corr(X1, X2) = p. The usual assumptions for a linear model hold in this case. You are interested in estimating B1. To accomplish this you collect a sample of the variables Y and X1 and estimate the following model Y; = Yo...
