Comparing predictive models vs. actual data

Postby jhm3 » Mon Nov 24, 2014 9:01 pm

I am trying to do my own analysis on a project that looks at the utility of different predictive models in predicting survival. I have the actual survival and would like to run the following tests: R2 (squared), root mean squared prediction error, mean absolute prediction error, and prediction bias.

I was able to run the R2 test but I cannot seem to figure how to do the rest of them! Could any one give me some pointers or links to videos that explain this process?
