...at" is the number of
categories of the dependent variable)
* Each case must be identified by a strata variable (id)
* Each duplicate must be identified by a variable indexing the
choices (newy)
* A dichotomous variable must indicate which duplicate corresponds
with the respondent's choice (didep)
I've done this as follows:
mclgen <- function (datamat,catvar) {
ncat <- nlevels(catvar)
id<-1:length(catvar)
datamat<-cbind(id,datamat)
perschoice <-NULL
for (i in 1:ncat) {
perschoice<-rbind(perschoice,datamat)
}
perschoice<-perschoice[sort.list(perschoice$id)...
