Regression Analysis, R Squared, Pseudo R Squared, Adjusted R Squared, Deviance.
We’ll look at one such alternative that is based on the following identity that we have come to know so well: Total Sum of Squares (TSS) = Residual Sum of Squares (RSS) + Explained Sum of Squares (ESS). While this identity works for OLS Linear Regression Models a.k.a. Linear Models, for nonlinear
