Summary of Fit Report

Rsquare

Using quantities from the Analysis of Variance report for the model, the R2 for any continuous response fit is always calculated as follows:

Adj Rsquare

Adj Rsquare is a ratio of mean squares instead of sums of squares and is calculated as follows:

The mean square for Error is found in the Analysis of Variance report and the mean square for C. Total can be computed as the C. Total Sum of Squares divided by its respective degrees of freedom. See The Analysis of Variance Report.
