Heckman SPSS error

Postby gabrielamp » Mon Jul 14, 2014 4:02 am

HI:
I was trying to download the heckman command and I believe I managed to do it.
It's available now on the menu analyze/regression/heckman

However, when I try to run I always get this error message:

"Error in dirname(fpath) : a character vector argument expected"

Anyone know what it means?
Thanks in advance
Gabriela

Hi Gabriela,

Could you post the URL where you got the Heckman extension? And can you share with us the syntax it generated?

Kind regards,
