Which is correct to find the value of the coefficient of determination (R2)?
A)SSR/SSE
B)SSR/SST
C)1 − SST/SSE

Question

Quizplus · Accepted Answer

The formula for the coefficient of determination (R2) is SSR/SST, where SSR is the regression sum of squares and SST is the total sum of squares. SSE is the error sum of squares and is not used in the calculation of R2. Therefore, option B is the correct choice. Option A is the formula for the F-statistic in a regression model, and option C is equivalent to 1 minus R2.
