How To Interpret R-squared and Goodness-of-Fit in Regression …

WebThe R-squared is not dependent on the number of variables in the model. The adjusted R-squared is. The adjusted R-squared adds a penalty for adding variables to the model that are uncorrelated with the variable your trying to explain. You can use it to test if a variable is relevant to the thing your trying to explain.
