Cost function in cv. glm for a fitted logistic model when cutoff value of the model is not 0.5
...ained from "Examples" section of ?cv.glm):
cost <- function(r, pi = 0) mean(abs(r-pi) > 0.5)
As I have a cutoff value of 0.2, can I apply this standard cost function or
should I define a different one and how?
Thank you very much in advance,
