-predict- does work in the usual way. The usual way is that -predict- works with the last model estimated, which is in your case for the last value of -splitting_var-. 

Clearly, however, this is not what you want. You could look at -statsby- or you could write code to save predictions one by one.

I would like to estimate a model on sub-sets of data using

bys splitting_var: regress y x1 x2 x3

and then predict (and plot) y at different values of x1 while holding x2 
and x3 constant at their mean values.

apparently -predict- does not work in the usual way after "bys 
splitting_var:  regress"

Is there any convenient way to do this?
