Is it possible to save the information matrix itself?

Or the likelihood score? I saw from an earlier post in 2008 that the likelihood score is not saved ( but am now wondering whether maybe this may have changed since then.

Is there some feasible method for recovering either? Thanks.

The information matrix cannot be saved. By likelihood score do you mean derviative?

Yes, that's right. Although now I just noticed a reply to a similar question back in March that stated:
"TECH3 is the inverted information matrix and that can be saved."

Is this correct? Thanks.

I forgot about that. TECH3 is the inverted information matrix and it can be saved. See the TECH3 option in the SAVEDATA command.
