qregpd

[Garima Maurya]

Dear all!
Getting error message r(3499) after running qregpd command. Please help!

Garima:
as per FAQ, it is impossible to help with no details from your side.
In addition, bumping is expected to hamper more than help.

I had a suspicion of what might be wrong, so I installed the qregpd community-contributed command available on SSC, and ran the first example.

. webuse nlswork
(National Longitudinal Survey of Young Women, 14-24 years old in 1968)

. qregpd ln_wage tenure union, id(idcode) fix(year)
                 <istmt>:  3499  mm_panels() not found
r(3499);

Note that presenting the entire output of the command - rather than just the error code - allows the reader to recognize that an apparently undocumented requirement of the qregpd command is the the moremata package also be installed. (I recognize the mm_ prefix on the function name, and in any event search mm_panels also takes me to the moremata package at SSC.) This is what I expected - too many developers have installed moremata and the forgotten that its commands are not part of base Stata.

After installing moremata using

ssc install moremata

the example ran to a successful conclusion.

Please take a few moments to review the Statalist FAQ linked to from the top of the page, as well as from the Advice on Posting link on the page you used to create your post. Note especially sections 9-12 on how to best pose your question. It is particularly helpful to copy commands and output from your Stata Results window and paste them into your Statalist post using code delimiters [CODE] and [/CODE], and to use the dataex command to provide sample data, as described in section 12 of the FAQ.

The more you help others understand your problem, the more likely others are to be able to help you solve your problem. And the sooner you are likely to find someone who can help.
