A residual is:
The difference between the regression prediction of y and its actual value.
Explanation : the above option for residual isthing but the definition of residual.Residual is denoted by e = predicted y - actual y.Reisdual is a error that is not explained by regression line.
We can see the residuals in regression as , the vertical distance between the regression line and given observations lie above and below the line.

Which statement is not correct? Multiple Choice R-squared is a measure of the degree of variability in the dependent variable about its sample mean explained by the regression line. The adjusted R-squared measure should be used in the case of more than one independent variable. The null hypothesis that R2 = 0 can be tested using the F-statistic. Forecasters should always select independent variables on the basis of R2. All of the options are correct.
