= SST = SSE = SSR. so that SST = SSE + SSR. The R2 is the fraction of the variation in y that is explained by the estimated model, and thus measures goodness of fit. It is defined as: R2 = SSE/SST = 1 – SSR/SST. The R2 can also be interpreted as the square of the correlation between y and ŷ. Unbiasedness & Omitted Variable Bias ................
