The output of a different regression analysis on the effect of radio advertising spending, television advertising spending and online advertising spendingon sales is given below. For this study they explored 3 different types of advertising spending (radio, television and online). They modelled it asy = ao + a1¤1+a2x2 + a3X3 .
