Hi all,

Using Stata 17, I am trying to run coarsened exact matching commands (i.e., -cem-) introduced in this Stata Journal article: https://www.stata-journal.com/articl...article=st0176

Please note that the article's data file cannot be opened using the suggested URL. I found this public data ( Array ) somewhere on the net and attached it here.

There are multiple troubles with this command. But the main issue is that after I run the following command (from the journal article):


Code:
cem age education black nodegree re74, treatment(treated)
I get this error:

cemStata(): 3001 expected 8 arguments but received 7
<istmt>: - function returned error
This issue is raised in an old thread: https://www.statalist.org/forums/for...lems-using-cem

But, it is not clear how it is resolved. Does anyone know a way around this issue? Is there an official command for CEM in Stata? I hope Stata can solve this issue by adding a properly vetted command.

Thanks,
Navid
