Error when running mmqreg with abs() function and interaction term

[Isabelle Mary]

Hi,

I am running a multivariate quantile regression using mmqreg and am running into an error message when using an interaction term and the abs() function.

Sorry in advance, I have to run STATA on an offline server for data protection reasons that does not allow me to copy/paste or export so I cannot copy & paste data or code into here.

My regression looks like this:

mmqreg score portion_meal_r score_pre wealthscore disability_bin satis1 hwise#portion_meal_r, cluster(settlement2) abs(settlement2)

When I run it, I get the following error message:

_i__1__hwise_X_1__portion_meal_r invalid name

st_addvar(): 3300 argument out of range
map_solve(): - function returned error
<istmt>: - function returned error

When I run this without abs(settlement2) or without the interaction terms it runs without issue.

Hi Isabelle
could you try again, but renaming your variables?
Say, rather than using "portion_meal_r" use pmr
and rather than hwise use "hw"
Thank you

Thank you Fernando!! I tried this and it is now giving me the error message: _i_ ambiguous abbreviation
Still only occurring if I'm using the abs() function
Any thoughts? Thanks again

Do you think you can send me an email with your data (or some other data) so I can try and replicate the error?
Thank you!

I can't export the data from the offline server, unfortunately, but let me see if I can recreate some data...what is your e-mail? Thanks!!!
