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...

I have uploaded a new package to CRAN called ProDenICA. This fits ICA models directly via product-density estimation of the source densities. This package was promised on page 567 in the 2nd edition of our book 'Elements of Statistical Learning' (Hastie, Tibshirani and Friedman, 2009, Springer) . Apologies that it is so late. The method fit...

...g/packages/pROC Tools for visualizing, smoothing and comparing receiver operating characteristic (ROC curves). (Partial) area under the curve (AUC) can be compared with statistical tests based on U-statistics or bootstrap. Confidence intervals can be computed for (p)AUC or ROC curves. * ProDenICA (1.0) Trevor Hastie http://crantastic.org/packages/ProDenICA A direct and flexible method for estimating an ICA model. This approach estimates the densities for each component directly via a tilted gaussian. The tilt functions are estimated via a GAM poisson model. Details can be found...
