For the 76 election, I did my dissertstion using a 205 * (10*10) SINDSCAL. I
just retired and everything is in boxes, but over time I intend to look at all
my VAX tapes to see what should be preserved. At that time I translated
SINDSCAL to VAX Fortran which allows you to use PARAMETER statements and
compile to fit your problem.
Is this the kind of thing you are looking at? Are you more interested in
single matrix MDS?
I have worked with large data sets from Social Security, IRS, DoD, Medicare,
Census, etc. I may very well come across needs in my future consulting.
(e.g., I was approached by the National Statistics Office of the UK.)
In the 70's I did a lot of clustering of counties, I have tossed around the
idea of doing 1) clustering of all the counties and/or 2) generating R
matrices for each county and INDSCALing those data.
