Re: how can I do Principal Components Analysis with octave?

[Henry F. Mollet]

I believe you would need the programs doing the work. They are called
functions in Octave or Matlab, something like "PCA.m". I would be interested
myself so I checked using Google what MATLAB has:

Here is a list of the functions with a short description of each:
PRINCOMP - principal components from raw data matrix
PCACOV - pca from covariance matrix
PCARES - residuals from pca
BARTTEST - Bartlett's test for dimensionality.

Next I checked for the first two, namely "PRINCOMP" and "PCACOV" in
octave-forge but apparently neither is present. I guess we're out of luck
for the time being unless we have the capability to write the program.
