Problem creation tensor
...if you're talking about
working/living occupation)
so you can't create a tensor n users x m items x 21 occupations
but you can build the contingencies of preferences m items x 21
occupations x 5 ratings
One way to build your tensor m x 21 x 5 is:
M1 is the first occupation (users x m) ...
UserItem <-rbind(M1,M2, ...M21)
m=1682
for (j in 1:m){
UserItem[,j] =factor(UserItem[,j],levels=1:5)
}
occ=factor(c(rep(1,dim(M1)[1]),rep(2,dim(M2)[1]),
...,rep(21,dim(M21)[1])),levels=1:21)
Z <- array(rep(0,m*21*5),c(m,21,5),
list(paste("item",1:m,sep=""),paste("Occ&qu...
