The Least Squares Equation $y=3+4 x_{1}+5 x_{2}$ Is Considered to Be a Better Predictor Of

Short Answer

The least squares equation $y=3+4 x_{1}+5 x_{2}$ is considered to be a better predictor of $y$ than the least squares equation $y=7+5 x_{3}$ , if the multiple correlation coefficient is __________ than the absolute value of the correlation coefficient involving $x_{1}$ and $x_{3}$ .
