Question

Describe the process of measuring the accuracy of the regression estimates?

Expert Solution

Step 1

Standard error is used to measure the accuracy. The standard error is used to find the range of actual value around the regression line. It can be computed using two formulas.

One formula is $S E = \sqrt{\frac{\sum_{}^{} {(y - \hat{y})}^{2}}{n - 2}}$ , where y is the actual value in sample, $\hat{y}$ is predicted value by the regression line and n is the sample size.
