Error when producing graph using pbalchk

[Jake Magel]

Hello, I am trying to use the user written command pbalchk to check balance after IPW.

ely_dly is my matching variable.

When I run this code:
pbalchk ely_dly agecatdum1 agecatdum2 agecatdum3 agecatdum4 agecatdum5 agecatdum6 agecatdum7 ///
mental_rc neck_rc smoke obese sud_rc elixsum muscle_relax nsaids opioid_rx oral_steroid ch_pn_rc , wt(ipt_wt) graph

it produces the desired graph

When I run this code:
pbalchk ely_dly agecatdum1 agecatdum2 agecatdum3 agecatdum4 agecatdum5 agecatdum6 agecatdum7 ///
mental_rc neck_rc smoke obese sud_rc elixsum muscle_relax nsaids opioid_rx oral_steroid ch_pn_rc lx_surg , wt(ipt_wt) graph

I get an error that says may not label 15.5 with lx_surg included

dataex only allowed a smaller number of variables that I am actually trying to use, so below is an abbreviated list. Interestingly, when I have ch_pn_rc in a line that includes more variables, I get the same error message but not with a smaller number of variables.

Can anyone provide advice to help me produce the graph with ch_pn_rc and lx_surg included?

Thanks, Jake

Hi Jake,

Did you figure out this problem? I actually have the same problem. I get "may not label 11.5" after I run "pbalchk $treatvar $pvar, wt(weight) graph", but I have no clue how to solve this. I have 30 or covariates in $pvar. I appreciate your help!

Best,
Huiying

[Mark Lunt]

This happens if two variables have the same standardised difference between treated and untreated before adjusting. To fix it, you need to edit pbalchk.ado (find out where it is on your computer with the command "which pbalchk"). Then search for the line beginning "egen rank" and add ", unique" to the end of the line. The command should then work

Hi! I am having the same exact error Jake had. I did exactly what Mark said, the only thing my pbalchk.ado already had ", unique" at the end of the indicated line! I still can't get the graph that I want from the pbalchk. Is there any other way to get the graph option work?

Thank you,
Ghadah
