Atesh,
I am not sure how useful it will be to cluster 17 12-variate observations
(subjects) using (presumably) Gaussian model-based clustering, but you may look
at the following paper:
Chen, W.-C. and Maitra, R. (2011). Model-Based Clustering of Regression Time
Series Data via APECM
? An AECM Algorithm Sung to An Even Faster Beat. Statistical Analysis and Data
Mining, 4:567-78. DOI
information: 10.1002/sam.10143.
There is R code available (not R package), but again, it is not clear to me how
useful this is going to be unless there is a structure in the 12 variables you
are willing to give in (of course, unless I have misunderstood the context of
your question).
Best wishes,
Ranjan
