Sir, I am using gretl-2018a with retobit 0.9 version.
"Invalid option '--opg' appeared.
OK, mystery solved: As the changelog shows
(
http://gretl.sourceforge.net/ChangeLog.html), gretl added the --opg
option to the tobit (and intreg) commands only in version 2019b. Sou you
need to upgrade gretl and hopefully then it should work.
@Jack: Accordingly the retobit package needs to require at least 2019b
please.
thanks
