"orth_out" balance tests generating "variable __000000 already defined" errors

[Yan Liu]

Hi all,

I am running the "orth_out" command in Stata 18 to conduct a series of balance tests for an experimental study. The codes based on the help file is simple, but I keep running into "variable __000000 already defined" errors. This happens even if I replace the local with a single variable's name. When I test out the orth_out command using the auto dataset, "orth_out mpg, by(foreign)", the code runs fine. Any help would be much appreciated. Thanks!

Below are my codes:


* Preliminary steps

clear all
set more off
cap log close

* Import data

use "clean data/mkv_ng_men_merged_na.dta", clear

* Balance test

// macro drop _all

local ctrl dem_literacy_ws_pre dem_age_ws_pre dem_marital_otherwives_ws_pre ///
dem_household_size_ws_pre dem_children_ws_pre assets_index_ws_pre ///
dem_religion_ws_pre dem_religiosity_ws_pre dem_education_ws_pre ///
dem_hh_income_ws_pre dem_personal_income_ws_pre

orth_out `ctrl' using "tables/balancetest.tex", by(treatment) proportion ///
test se replace latex

exit, clear

orth_out is a community contributed command. Would you please provide a data example using the -dataex- command? Would you please also type set trace on into the console, run the orth_out command, then post the output along with your data example? You should then type set trace off into the console to clean up.
