...some solution in the following problem. The following error appears when i use "mgcv" package for implementing GAM. But the same formula works fine in "gam" package. > model.gam <- gam(formula = RES ~ > CAT01+s(NUM01,5)+CAT02+CAT03+s(NUM02,5)+CAT04+ + CAT05+s(NUM03,5)+CAT06+CAT07+s(NUM04,5)+CAT08+s(NUM05,5)+CAT09+ + CAT10+s(NUM06,5)+CAT11+NUM07+CAT12+CAT13, + family = binomial(link = logit), data = train.data,na.action = na.exclude, + control = list(epsilon = 0.001,bf.epsilon = 0.001, maxit = 50, + bf.maxit = 10, trace = F)) Error in terms.formula(reformulate(term[i...

Dear Users, In case of ridge logistic regression, i want to calculate the optimum penalty using aic and bic criteria. Here is the sample code: fit <- lrm(RES ~CAT01+NUM01+NUM02+CAT02+CAT03+CAT04+NUM03+CAT05+CAT06+NUM04+ CAT07+CAT08+NUM05+NUM06, data = train.data, x = TRUE, y = TRUE) pentrace(fit, penalty = list(seq(.001, 5, by=.1))) output: Best penalty: penalty df 1.001 13.26012 Var1 df aic bic aic.c 1 0.001 13.99894 337.7431 279.2273 336.8458 2 0.101 13....
