Problems with regressions (regress.ado r(199)

[Anthony Dristig]

Hi,

I have run into some problems with making regressions in Stata (version 16). I have been using Stata on my Macbook Air (mid 2017) for about a month without any problems. Now from out of a sudden I get the error message "command Regress not defined by Regress.ado r(199);" when I try to do regressions. I have tried to reinstall the software but it did not help. Does anyone have any suggestions on how I can fix this?

Anthony:
welcome to this forum.
have you reinstalled the last updated version of Stata (that is, from Stata webisite)?
If that were thae case, I'd address you question to https://www.stata.com/support/tech-support/contact

Anthony Dristig commands in Stata are case-sensitive. Instead of typing Regress, use regress.

Anthony:
Hemanshu is correct and his reply is much more helpful than mine:

. use "C:\Program Files\Stata17\ado\base\a\auto.dta"
(1978 automobile data)

. Regress price mpg
command Regress not defined by Regress.ado
r(199);

This reminds me about the importance of sharing exactly what you typedna d
