Package File already exists despite Package not found

[Kyle Brees]

I am trying to install a Chi-Squared Goodness of Fit package into Stata 15.1 but each time I try to install it I receive an error message (see below) this happens even with the . When I try to uninstall the package is not found.

 ssc install csgof
checking csgof consistency and verifying not already installed...
installing into c:\ado\plus\...
file c:\ado\plus\next.trk already exists

ssc uninstall csgof
package not found

I am not sure how to remove that package or how to install a package so that I can run the chi-square goodness of fit, or uninstall a package that doesn't exist.

-csgof- is not on SSC, it appears. It's at the UCLA site. See below

. ssc install csgof
ssc install: "csgof" not found at SSC, type search csgof
(To find all packages at SSC that start with c, type ssc describe c)
r(601);

. search csgof

.==========================

To find the precise directory in which you've installed -csgof-, type

which csgof, all

[Nick Cox]

As it has been mentioned,

1. csgof is limited in not supporting if or in qualifiers

2. The help file reports it as testing a hypothesis about percents, which the code fortunately implements as a test of a hypothesis about frequencies.

Those qualifications don't apply to chitest or chitesti -- which are from SSC and in the package tab_chi.

Thank you for that, is there a way to uninstall packages not on the ssc list? I have tried to install tab_chi but I received the same error as above.

[Nick Cox]

Naturally. ssc (in the last millennium I was second author of the first version) is just a wrapper for other commands, so see the help for ado.

Otherwise, your next.trk seems messed up. I don't think it's especially dangerous to delete it, but it's at your risk. What you could do is rename it and see whether you can live without it. .
