The following estimated regression equation was developed for a model involving two independent variables. ☺ = 40.7 + 8.63x, + 2.71X, After x 2 was dropped from the model, the least squares method was used to obtain an estimated regression equation involving only x 1 as an independent variable. û = 42.0 + 9.01% when a. In the two independent variable case, the coefficient x 1 represents the expected change in Select corresponding to a one unit increase in Select Select is held constant. In the single independent variable case, the coefficient x 1 represents the expected change in Select corresponding to a one unit increase in Select b. Could multicollinearity explain why the coefficient of x 1 differs in the two models? Assume that x1 and 2 are correlated. Yes, because a change in x1 would be accompanied by a change in x2
