The correct statement about the residual in the context of
regression analysis is:
[4] c — It is the difference between the observed and predicted
values of the dependent variable.
Residuals represent the vertical distance between the actual
data points and the regression line. They are not the slope of
the regression equation or the correlation coefficient.
To indicate a good fit of the model in multiple regression
analysis:
[1] b — A high R2R^2R2 value.
