RE: st: lock variable in model so that swaic cannot remove it

[Neophytos Stylianou <neophytos.stylianou@postgrad.manchester.ac.uk>]

Thanks Nick

Sorry for not having all details there. It is my first time in statalist. Ill make sure next time I will be more descriptive.

By the way is there another way of getting an optimal model similar to swaic?

Thanks,
Neo

-swaic- is a user-written command. Please remember that you are asked to explain where user-written commands you refer to come from. In this case I doubt that either author is a member of the list, and I know that Tom Steichen is very firmly retired.
