Interpretation is facilitated by calling - mfx-. Note, though, that your
case is special in that X1 and X1 squared will move in tandem. See -nl- as a
solution to that...

Subject: st: Interpreting Poisson regression results with squared term
Hello All:
I recently posted a question on autocorrelation in Poisson regression, and I
was very happy with the responses I received.
Now I have a question about interpreting my results.
I ran a Poisson regression in which # of groups founded per year was the
dependent variable. My independent variables of interest are X1 and
X1-squared. The results were as follows:
Independent Variables
Constant 4.655
X1 .5334**
X1-squared -.6439**
X2 -1.176
X3 -.0734
