Indicating non-existent control variables in esttab

[Stefan Sliwa]

Dear Statalist,

I vaguely remember that there is a way to produce esttab tables, indicating whether controls which are not part of any stored results exist or not. Unfortunately, I do not recall the exact way and I cannot seem to find the solution.

Please see the example provided below which results in the error message "coefficient *.foreign not found". I know that this is exactly what is happening, but due to reasons of convenience I would like the command to produce a table which indicates that there is indeed no control variable "foreign" in the stored regressions.

Thank you very much for your help, I really appreciate it.

Best wishes,
Stefan Sliwa

* Load data
sysuse auto.dta, clear

* Run the regression (stored automatically)
reg price weight length

* Display stored regression results
esttab, se keep(weight) indicate("Foreign = *.foreign")

estout is from SSC (FAQ Advice #12). The rationale for -indicate- is that some models have the indicated coefficient(s) and some don't. If they all do not, there is nothing to indicate and you can just add a note that all models do not include whatever is to be indicated. Alternatively, use -estadd local-, but if all columns have the words "No", they are not informative.
