Summary of Fit

The Summary of Fit table contains summary statistics including Root MSE and R-Square. The Root MSE value is 0.6998 and is the square root of the mean square error given in the Analysis of Variance table. Root MSE is an estimate of ${{\sigma}}$ in the preceding regression model. The R-Square value is 0.2046, which means that 20% of the variation in GPA scores is explained by the fitted model. The Summary of Fit table also contains an adjusted R-square value, Adj R-Sq. Because Adj R-Sq is adjusted for the number of parameters in the model, it is more comparable over models involving different numbers of parameters than R-Square.
