The error 'option robust not allowed' in the "Oaxaca_rif" command

[Kim Myounghwan]

Hi. I am going to use the "Oaxaca_rif" command.

However, although I run the example in the help file, I encounter the following error.

What is the problem and how can I fix it?

Hi Kim
you need to update the oaxaca command
Please type
ssc install oaxaca, replace
and if the problem persists, just send me an email.
Thank you
Fernando
