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 R? 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.
