Define 11 as an interaction variable created from two binary variables, D1 and D2. Suppose we have a regression model containing only the variables D1, D2 and 11. Then, the sum of the regression coefficients on D1 and 11 will be: The average value of Y when D2=0. The effect of D1 on Y when D2=1. O The average value of Y when D2=1. O The effect of D1 on Y when D2=0.
