The output of a different regression analysis on the effect of radio advertising spending, television advertising spending and online advertising spending on sales is given below. For this study they explored 3 different types of advertising spending (radio, television and online). They modelled it as y = ao + a1¤1 + azT2 + azT3 . The table below gives the output of this regression analysis. Regression Analysis: Sales versus Spend Analysis of Variance Source DF MS F-Value P-Value Regression dfreg 23991.2 MSR F-val p-val Error dfer 561.7 MSE Total 111 24552.9 How many degrees of freedom does the Error (SSE) have? It is denoted by dferr in the table above.
