similar to: Explained variance for ICA

Hi all, Does anyone know how to get the independent components and loadings from an Independent Component Analysis (ICA), as well as principal components and loadings from a Pricipal Component analysis (PCA) using the fastICA package? Or perhaps if there's another way to do ICAs in R? Below is an example from the fastICA manual (http://cran.r-project.org/web/packages/fastICA/fastICA.pdf)

A colleague suggested that some R software was available for estimating "Independent Components Analysis" (ICA) (... signal separation). If so, I''d appreciate any pointers .

Does anyone know of an ICA (independent components analysis) package for R? In particular I'm looking for an implementation of the FastICA algorithm.

Hi all, I'm new to PCA in R, so this might be a basical thing, but I cannot find anything on the net about it. I need to make a PCA plot with two response variables (df$resp1 and df$resp2) against eight metabolites (df$met1, df$met2, ...) and I don't have a clue how to do... and I've only used the simplest PCAs before, like this: pcaObj=prcomp(t(df[idx, c(40:47)]))

Hi, I'm trying to use fastICA package but I only get an error message like following. > library(fastICA) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/usr/lib/R/library/fastICA/libs/fastICA.so': /usr/lib/R/library/fastICA/libs/fastICA.so: undefined symbol: sgesdd_ Error: package/namespace load failed for 'fastICA' Here's the

Hi everyone It looks like repeated runs of fastICA produce quite significantly different mixing matrices (not only in terms of sign and row order). I'm not a specialist, so would appreciate any advice on whether this should really be the case: > res3 = > fastICA(af[,2:20],4,alg.typ="parallel",fun="logcosh",alpha=1,method="C",row.norm=TRUE) colstandard >

Hi, I'm looking at the "cocktail party" classic problem. I can see how to use ICA to separate the components. But, How do I then create new wav files of the separated sounds so that they can be played?

I have been playing around with the FastICA algorithm in R, and I have come across the following issue. I'm new to this topic, so I'm hoping someone will be able to shed some insight. We know that the variance of the Independent Components is constrained to be 1 and they are uncorrelated, so the sum of squares of the coefficients of the mixing matrix (a$A) will give the variance of the

Dear list I have a vector of values that allegedly have a bivariate normal distribution. I want to create a plot that shows the values I have obtained, and the bivariate normal distribution curve for the data. Is there a way of doing this in R?

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

Hi, Looking at the fastICA library. I want to test separating out different sounds from a recorded wav file. But, I only have a SINGLE stream of data (one channel wav.) It appears as if the fastICA won't let me separate more sounds than I have columns in my data matrix. is this correct? If so, is there a work around that is commonly used? Thanks. -- Noah Silverman UCLA Department of

I've committed this diff. Please test and confirm that it works ok.

Hello , I have a general question: What does it means that a package was removed from the CRAN repository? There were problems in the package? I want to use 'mlice' package, but the package doesn't exist in the CRAN now and I worry about... I will be very thankful for the answer! Pavel [[alternative HTML version deleted]]
