Unit 2 assignment – marketing regression
The formula for a multiple regression is: Y = β0 + β1X1 + β2X2 + β3X3
Where Y is the dependent variable (Sales), X1 is Social Media, X2 is Web, and X3 is Print.
To calculate the coefficients (β) of each independent variable, we need to use least squares estimation. The results could look like this:
Y= 4500+50*Social Media + 200*Web – 100 *Print
