While Excel is nice for simple statistics (≤ simple linear regression analysis), it is often not good to use for anything more complex. Note that a R package called “Rexcel” is available that allows you to use R within Excel.

Fit a multiple linear regression model to these data. Perform a residuals analysis using graphical methods discussed in class (you do not have to plot a normal curve on the histogram of your residuals). Test for the significance of the regression at α = 0.05. Use the t-test to assess the contribution of each regressor to the model.

Note that simple linear regression is a special case where k=1, thus the methods used are just basic extensions of what we have previously done. Yi = 0 + X1i + ... + kXki + i where j is the change in mean for Y when variable Xj increases by 1 unit, while holding the k-1 remaining independent variables constant (partial regression coefficient).

There are two reasons for using this transformation to the original model variables. First in regression analysis we predict the expected value of any dependent variable based on any particular set of values of the independent variables. And estimation of the parameters of the model based on the set of independent variables must be more efficient.

Linear regression has many practical uses. Most applications of linear regression fall into one of the following two broad categories: If the goal is prediction, or forecasting, linear regression can be used to fit a predictive model to an observed data set of y and X values.
