Suppose that the sample regression equation of a model is $=4+1.5 x_{1}+2 x_{2}-x_{1} x_{2}$ . If we examine the relationship between $x _ { 1 }$ and y for four different values of $x _ { 2 }$ , we observe that the four equations produced differ only in the intercept term.

The Answer of Suppose that the sample regression equation of a model is $=4+1.5 x_{1}+2 x_{2}-x_{1} x_{2}$ . If we examine the relationship between $x _ { 1 }$ and y for four different values of $x _ { 2 }$ , we observe that the four equations produced differ only in the intercept term.

Suppose That the Sample Regression Equation of a Model Is =4+1.5x1+2x2−x1x2=4+1.5 x_{1}+2 x_{2}-x_{1} x_{2}=4+1.5x1​+2x2​−x1​x2​
