Coefficient of Determination
The coefficient of determination is given by r2 i.e., the square of the correlation coefficient. It explains to what extent the variation of a dependent variable is expressed by the independent variable. A high value of r2 shows a good linear relationship between the two variables. If r = 1 and r2 = 1, it indicates a perfect relationship between the variables.
