prediction error for test set-cross validation
...data into 10 folds for cross validation. I build logistic regression model
as:
>model <- glm(qual ~ AgGr + FaHx + PrHx + PrSr + PaLp + SvD + IndExam +
Rad +BrDn + BRDS + PrinFin+ SkRtr + NpRtr + SkThck +TrThkc +
SkLes + AxAdnp + ArcDst + MaDen + CaDt + MaMG +
MaMrp + MaSh + SCTub + SCFoc + MaSz,
family=binomial(link=logit));
Where the variables are taken from the trainSet of size 1989x31. The test
set is sized 222x31. Now my question is when I try to predict on the test
set it gives me the error:
> predict.glm(model, testSet, type ="response&...
