Dear Colleagues
I using North Textbook example for Linear regression model (and Chapter04.csv data set) and using apply model operator and performance (regression) operator to get model performance metrics for the linear regression model
Rapidminer Performance (Regression) operator provides R Square but not the adjusted R Square value
If there anyway I can get Rapidminer to calculate and provide adjusted R Square value - formulae is 1 - ((1-R Sq) (N-1) / (N-P-1)) where N = Sample size; P = Number of Predictor/Independent variables and R Sq = R Square value
Any help/clarification on above will be much appreciated
Kind regards Michael
