Question:

Consider the following model:

yn = 5 + 3x1 + 5x2

a. Provide an interpretation of the coefficient of x1.

b. Is the interpretation provided in part a true regardless of the value of x2? Explain.

c. Now consider the model yn = 5 + 3x1 + 5x2 + 4x1x2. Let x2 = 1. Give an interpretation of the coefficient of x1 when x2 = 1.

d. Repeat part c when x2 = 2. Is the interpretation provided in part a true regardless of the value of x2?

Explain.

e. Considering your answers to parts c and

d, what type of regression components has conditional interpretations?
