I cannot underststand all this. It seems that
you downloaded Jeroen Weesie's -pca- program and
got some results, but do not believe them and now want
for some reason to reinstall it. I predict that if you
reinstall this program you will get the same
results as previously.
There are no restrictions on the availability
of Jeroen's -pca-. Also, if you installed
it once, the same method should work again,
and there should be no need for private
If you referring to official Stata's -pca-,
then it will not work with Stata 7, quite
apart from ethical considerations.
In any case, with Stata 7 principal components
analysis, classical sense, is if I remember
correctly obtainable with -factor, pc-. Do
not invoke the -factor()- option.
Incidentally, it is my experience both
on Statalist and elsewhere that expressing
"urgency" is usually counter-productive. The
number of people likely to jump to it just
because you think you deserve an especially quick reply
is typically exceeded by those more likely to
delete your posting on precisely those grounds.
