The model y = β₀ + β₁x₁ + β₂x₂ + ε is used whenever the statistician believes that,on average,y is linearly related to:

Question

Quizplus · Accepted Answer

The model includes both x₁ and x₂ as predictor variables but assumes that there is no interaction between them. Therefore, both options a and b can be considered as potential linear relationships between the response variable y and the predictor variables.

The Model Y = β0 + β1x1 + β2x2

The Model Y = β₀ + β₁x₁ + β₂x₂
