Hi, We got a question about interpretating R-suqared. The actual outputs for a test dataset is X=(x1,x2, ..., xn). model 1 predicted the outputs as Y1=(y11,y12,..., y1n) model n predicted the outputs as Y2=(y21,y22...
I wrote a .R file (see below)to calculate robust measure of correlation using cov.rob. I got different correlation coefficients (0.70, 0.79, 0.63, ...) when I run the file different times. Can you tell me what this...

Hi, Thanks for your message. I tried to prove that the R-squared of the averaged model is always greater than or equals to the average R-squared of individual models (supposed m=2), Please see the attached r2.pdf...
