"First: how do I post a message on list serve?"
Replying to a continuing thread is not the way to go! See the FAQ at the
bottom of every post! Welcome to the list anyway :-)
"Second: I need to calculate an R squared change from two panel
regressions.
What is the best way to do this? The reviewers have asked for hierarchical
results, so I need to have incremental changes to the R square. Is this
possible?"
Could be many things. -nestreg- comes to mind...

Dear Chris,
I am a new user to Stata and am terribly confused.
First: how do I post a message on list serve?
Second: I need to calculate an R squared change from two panel regressions.
What is the best way to do this? The reviewers have asked for hierarchical
results, so I need to have incremental changes to the R square. Is this
possible?
Thanks so much for your help on this Sunday evening.
Take care,
Seema

Subject: Re: st: Stata 10 is Malware (also version 11?)
Filipa,
I'm still curious: did your students discover that they had all been
using illegal versions of the software and that this was likely
causing the problem? And were entire variables being dropped after a
particular operation was conducted?
I'm just a little concerned that, if this type of capability is built
into the program to prevent piracy, it could accidentally occur even
on legally installed versions. Perhaps someone with advanced computer
or programming knowledge would find the suggestion ridiculous, but I
find that several day-to-day programs often don't function as they
should (a windows user could probably guess which company's mediocre
software I'm referring to) so it is a bit disconcerting to think that
STATA might suddenly develop a "glitch" and drop part of the dataset
being used.
If it is merely dropping of variables, I suppose it should be obvious
if this were to ever happen. But if it applies to observations as
well, the potential for a glitch to occur might be cause for concern.
It also makes me wonder if it wouldn't have been better to just design
STATA to just not work altogether when unauthorized licenses or
activation keys are used.
Best wishes,
Chris
