Hi, I am running the non-parametric rasch model tests using eRm. I have a
reasonably large dataset for this type of exercise (110 items, 248 persons).
I run:
> allb2=as.matrix(allb)
> rsample <- rsampler(allb2, ctr)
> t102<-NPtest(rsample, method="T10") #global test, subgroup inv
and receive error message as follows.
"Error in m[idx1, idx2] <- 1 : subscript out of bounds"
Using the same code for a different dataset does not cause this problem.
Any suggestions much appreciated!
(ctr spec:
burn_in = 100
n_eff = 1000
step = 16
seed = 0
tfixed = FALSE )
