Polychoric package?

[Stacy Rosenbaum]

Hello,

I need to install the polychoric package, but unfortunately, as others in the forum have previously reported, it seems to have disappeared from the web. If you have it and could send the .ado and .hlp files, I would be very grateful! Not sure if it matters, but I am running Stata 13.

Cheers, Stacy

Hi Stacy. Have you tried net install polychoric?

. net describe polychoric

First, a note: for the net describe command to produce the output shown above, the from directory must already be set to the location given. The fully general command is

net describe polychoric, from(http://staskolenikov.net/stata)

The description shown in post #2 states that version 1.4 is the current version, but net install polychoric from that location actually installs version 1.5 (per the comments in polychoric.ado), which to the best of my knowledge is the latest version. Apparently some of the metadata at that location used by the net command is outdated.

Let me also add that the author has always more-or-less hidden the visibility of the files on his web pages; browsing to them does not produce links to downloadable files. That's why it appears at first glance that the software is not available on the web.

Hello,
Has anyone been able to locate the polychoric package since this 2018 posting? I have not been able to locate the files for installation anywhere. I need the program so that I can rerun some code previously written by a colleague. Any help would be greatly appreciated. Thanks much.

The one small twist needed after

search polychoric

is that Stata is reluctant to copy from http:// sites. However, this works fine for me

net describe polychoric, from(https://staskolenikov.net/stata)

after which I could install successfully. Where do I send the invoice?

Thank you !

Good day all.
I am trying to install polychoric pca on Stata 15 (by Stas Kolenikov) but I have not been able to. I have used the link suggested by users (e.g. Nick Cox):
