Statistical Details for the Summary of Fit Report

This section contains details for the Summary of Fit report in the Bivariate platform.

RSquare

Using quantities from the corresponding analysis of variance table, the RSquare for any continuous response fit is calculated as follows:

RSquare Adj

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

The mean square for Error is in the Analysis of Variance report (Figure 5.11). You can compute the mean square for C. Total as the Sum of Squares for C. Total divided by its respective degrees of freedom.

Note: RSquare and RSquare Adj are not reported when a constraint is placed on either the intercept or the slope.
