I assume that there is a simple way to do this, but I haven't been able to
find out how.  I would like to construct a scale based on n items where
each item is weighted in proportion to its factor loading.  My clunky way
of doing it is to construct the scale myself by (a) accessing the matrix
of loadings e(L), (b) multipling each item by its loading, and (c) adding
them up.  Any advice about a simpler way to do this will be greatly
appreciated.
