Does anybody how to interpret the results of the "principal component analysis"
obtained by typing the command line:
    pca varlist [if] [in] [weight] [, options].
I haven't found any in the manual.

You didn't really type:
    pca varlist [if] [in] [weight] [, options]
did you?

As of Stata 9 -pca- is described in the [MV] manual (multivariate statistics),
with several examples; in Stata 8 is was in [R].

Happy New Year
