...some help.
I want to obtain a cross validation for a regression model (binary response)
but I got an error with CVbinary. Well I did this:
fit <- lm(resp ~ PC1 + PC2 + PC3 + PC4 + PC5 + PC6 + PC7 + PC8 +
PC9+PC10+PC11+PC12+PC13+PC14+PC15+PC16+PC17+PC18+PC19+PC20+PC21+PC22+PC23+PC24+PC25+PC26+PC27+PC28,
data = dexp.cp, family=binomial())
CVbinary(fit)
Error in sample(nfolds, m, replace = TRUE) : invalid 'size' argument
I cannot understand this error, I was googling it, but i didn't find nothing
really helpfull. Can someone help with is?...It's really important.
