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: ## CANDE...

...so much item 4, for item 2 and 3 he hasn't expressed a rating, etc. I need to construct a tensor with n users, m items and 21 occupations. After I have construct the tensor I want apply Parafac. I read data from a CSV file and build each matrix for each occupation. Didier Leibovici (author of PTAk package) suggested to me: ok that's bit clearer you have 21 matrices ( 1 for each occupations) of users rating their preferences (from 1 to 5 but without rating all of them: missing values) of m items. but I suppose the users are not the same across the 21 occupations (one has only one occupa...

Hello, I would like to perform a generalized singular value decomposition with R. The only possibility I found is "GSVD" that is based on LAPACK/BLAS. Are there other possibilities too? If not, has anybody used LAPACK/BLAS under Windows XP? How can I install them? Following [1] did not help. I hope this is the right place for my question. Thank you very much! Oana Tomescu [1]

Dear R-users, I couldn't find a function or some help in R-project web about the Generalized Singular Value Decomposition. In MatLab there is a simple function for this algebric issue (gsvd). Is there anything like that in R? And, if not, could you help me to apply this method in R?
