No, the problem is that by first transforming the dependent
variable you are no longer modeling the average in y but the
average in log(y). If you want to study your effects in terms
of the original unit of y you'll have to use -glm- with the
-link(log) option rather than use -regress- with the
transformed dependent variable.
Hope this helps,
