Dear all, I have a sample with 920 observations. I want to create a loop which takes 300 of these observations for the prediction and the rest to estimate the model. My idea was to create something like this: cs.training.dat <- read.table... cs.training.dat_sub1 <- subset(cs.training.dat, Income>10) cs.training.dat_sub2 <- subset(cs.training.dat_sub1, Dept.Ratio<=1) cs.training.dat_sub3 <- subset(cs.training.dat_sub2, Credit.Limit.Ratio<=1) for (i in 1:500){ y.2 <- cs.training.dat_sub3$y[1+[i]:300+[i]] y.1 <- cs.training.dat_sub3$y...
