Dear list members,
I am using a cross validation of a generalised linear model (glm). The cv.glm
function (from boot package) returns an error as so-called ?delta? value. I
would like to get to a (cross-validated) squared q, because I want to directly
compare it to the squared correlation coefficient r.
I tried to find an an equation for the raw and/or adjusted cross-validation
estimate of prediction error. But actually I did not get a clear answer up to
now. So it would be very kind, if someone could help me with this.
Thanks in advance,
Markus
