Cannot find the powerreg program.

[Scott Vince]

I'm trying to install the powerreg command/program for regression power analysis but cannot seem to find it anywhere. Stata (I have version 11) tells me the program is not found and I cannot locate other posts with additional information on its whereabouts. Is it still available?

Thanks for any help.

I think you can still get it by running -net describe powerreg, from(https://stats.idre.ucla.edu/stat/stata/ado/analysis)- in Stata, and then clicking on the install link that appears.

When I input that command the program cannot retrieve/find anything:

. net describe powerreg, from(https://stats.idre.ucla.edu/stat/stata/ado/analysis)
unknown network protocol
https://stats.idre.ucla.edu/stat/stata/ado/analysis/ either
  1)  is not a valid URL, or
  2)  could not be contacted, or
  3)  is not a Stata download site (has no stata.toc file).

current site is still http://fmwww.bc.edu/repec/bocode/p/
r(671);

Scott, you can download a zip-file for -powerreg- here:

HTH.

Stata 11 whines about urls that start with https:. Do you have access to a later version, at least for the purpose of downloading?

EDIT: Crossed with Bruce's message. I explain the problem but Bruce provides the solution.

[Scott Vince]

Thank you everyone! Bruce's solution worked. I had no idea that Stata 11 struggled with https:

[Richard Williams]

Most things work fine with either http or https. But Stata is fussy about it. For example, use will not redirect from http to https. Notre Dame switched from http to https a few years ago and it zapped dozens of handouts and do files I had online. I finally just sat down one day and fixed them all.
