   Question

   Gegeven is de volgende geschatte regressievergelijking: $\hat{y} = 25+0.8x_{1}-3.5x_{2}+1.2x_{1}x_{2}$.

   Hoe ziet de regressievergelijking eruit voor $x_{1} = 10$?

   
   
   1. TRUE: $\hat{y} = 33+8.5x_{2}$
   2. FALSE: $\hat{y} = 45-3.5x_{2}$
   3. FALSE: $\hat{y} = 25+20x_{1}-3.5x_{2}$
   4. FALSE: $\hat{y} = 25.8-2.3x_{2}$
   
   

   Solution

   Vul $x_{1} = 10$ in de regressievergelijking en werk uit: $\hat{y} = 25+0.8 \times 10-3.5x_{2}+1.2 \times 10 \times x_{2} = 25+8-3.5x_{2}+12 \times x_{2} = 33+8.5 \times x_{2}$.
