Hi ALL, Recently I confronted with a error in using package ProDenICA, when let k<p (exactly the example code with k=1, http://finzi.psych.upenn.edu/R/library/ProDenICA/html/ProDenICA.html), Error in solve.default(V, W) : 'b' must be compatible with 'a'
I have examined the code of function ProDenICA(), but could not find the reason. And how large is the sample size N generally required for a stable and robust result? I tried a sample of N=30 and get a very fluctuated mixing matrix A with fastICA algorithm in package fastICA, and the results become quite stable for a similar sample with N=60.
