The following model: y = β0 + β1x1 + β2x2 + β3x1x2 + ε
A) is a linear model with interaction.
B) is a second order polynomial model.
C) is a composite model.
D) is a convex model.

Question

Quizplus · Accepted Answer

This model is a linear model with interaction because it includes an interaction term (β3x1x2) between two predictors (x1 and x2), which allows for the effect of one predictor on the outcome variable (y) to depend on the level of the other predictor.

The Following Model: Y = β0 + β1x1 + β2x2
