Dear list,

I am trying to use some of the commands from the spost package, but
something odd is going on.

I have estimated a logit regression and I tried to use any of -prvalue-
or -prtab-. Unfortunately the commands never report any result. For
example:


. prvalue
 
logit: Predictions for ew_undecided

  Pr(y=1|x):               .   95% ci: (     .,     .)
  Pr(y=0|x):               .   95% ci: (     .,     .)

[...]

Or


. prtab cw1_ew_exp~d 

logit: Predicted probabilities	of	positive	outcome	for
ew_undecided


cw1_ew_ex 
p_spd      Prediction

-2            
-1            
0            
1            
2            

[...]

So I can run the commands but they never show a prediction result. I
believe it is something very obvious and easy, but I just can't figure
out what it might be.. Any hints?


Daniel
