Cannot Install didregress command

[Huthayfa Nabeel]

Hi all,

I am trying to run a regression like the follwoing one:

didregress (satis) (procedure), group(hospital) time(month)

when I run the regression, I receive the following message

command didregress is unrecognized

I tried to install didregress as follow

ssc install didregress

this is what I received

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

I tried to find the installation. Unfortunately, I couldn't.

I am using Stata 14.2

Any help in installing didregress will be highly appreciated.

didregress is part of official Stata as of version 17 - what version do you have?

[Jared Greathouse]

It shouldn't be recognized, as it's part of native Stata

-didregress- is an official Stata command which was added after your version of Stata 14.

Your options are to

1. Find Stata 17

or

2. Find a user written version of difference in difference regression

or

3. Do the difference in difference regression manually, it is super simple.
