Hello, I used the cv.lm function to validate a linear regression model fit<-lm(y ~ x1+x2+x3+x4+0, data=mydata) without intercept I tried to validate the model by performing a leave one out cross validation procedure usinfg the cvlm function: CVlm(df=mydata, fit, m=196) But how can I get the adjusted R² from the output of this function. Or is there any other function to perform a leave one out cross validation procedure. Thank you very much in advance. A
