validation logistic regression
Hi
I did validation for prediction by logistic regression according to following:
validationsize <- 23
set.seed(1)
random<-runif(123)

salich<-profilesample$SALIC.H.1
salic.lr<-glm(salich~wetnessindex, profilesample, family=binomial('logit'))
summary(salic.lr)
salichpred<-predict(salic.lr, newdata=profilevalidation)
expsalichpred<-exp(salichpred)
salichprediction<-(expsalichp...
