Hello everybody,

in the past months I have developed a model to predict the mortality rate of Acute Myocardial Infarction Patients. My evaluation was mainly based on ROC Curves etc.
I have now been asked to calculate the R-Square of my model, another existing model in regards to the actual mortality rate. So far I have only found a function calculating a regression, and then the R-Square of the calculated Regression.
Is there a function to calculate the R-Square for existing models?

Thanks for your help

Katrin
