Dear All!

SPSS 13 produces regression estimates of factor scores properly
(imo). However the same syntax (40 items, scored from 1 to 5, PAF
solution, 5 factors rotated by Promax) produces odd results when
using version 14 to the same data.

Factor score correlation are small negative, they all should be
positive (and are in v13 solution), stardard deviations of the
scores exeed 1 slightly (not in v13), so this can not be the
multiple R ahcieved in estimation.

Factor scores produced with same syntax using same data and
versions 13 and 14 correlate abt .8 (I expected them to be
identical).

I give more details about syntax and data, if necessary.

Something has been obviously changed. Can someone explain?
