[R] Ptak and Candpara

[Peppe Ricci]

Hi,

I am using the package PTAK and in particular the command Candpara to
perform the Parafac factorizationor of a tensor.
The results are not encouraging as I expected, I'm starting a phase of
analysis to see if there are errors.
I pose a question and I hope you can help me.
The command to run the factorization is:

## CANDECOMP/PARAFAC
results<- CANDPARA(data_matrix, dim=3)

summary(results)

U<-results[[1]]$v
V<-results[[2]]$v
W<-results[[3]]$v

data_matrix is a tensor of 943x1682x4.

what I want understand is: U, V, W, are really the three factors that
I should get from factorization?
I hope someone can help me.
Thank you.
