glm step() fkt
2 messages · Schrabauke, R. Michael Weylandt
Put them in a list:
ModelList <- vector("list", 100)
....
ModelList[[i]] <- mod.step <- step(mod, direction="both",trace=T)
Then come back and use sapply() to do whatever you want to the set of
models to compare/count/etc them

Hi volks,
i have a question about the step() fkt. Is there a possibility to save the
last model generated from this method. I have a loop and so i generate 100
different models with the step fkt and i want to know which model is the
most common.
CODE:
...
missStep -> numeric(100)
for (j in 1:100) {
? ?trainindex <- sample(c(1:462),300)
? ?train <- data[trainindex,]
? ?test <- data[-trainindex,]
? ?mod.step <- step(mod, direction="both",trace=T)
? ? ? ? ? ? ? ? ? ? }
...
So i want to store each iteration the best model.
Thx in advanced people,
greetings
