Regarding the official example, I would need to make,
*************
sysuse auto, clear
bys foreign: pca trunk weight length headroom
and then create a new variable with the cumulative of the first
compenent
of each group (foreign or domestic)assigned to each "car".

-statsby- could be your friend, but you really need to frame your
question
in terms of an official example:
sysuse auto, clear
bys rep78: pca trunk weight length headroom

I am performing a PCA analysis of specific firms'(id) characteristics
(varname) within regions.
I would like to know if it possible to create a new variable with the
results of the cumulative of the first component to be assigned to each
firm (id).
