Re: st: -mfx-: can I just keep the interaction variable?

Richard,

You're right; that must be it, because when I drop vce(boot) the - 
mfx- works fine.  What's a good solution for calculating the marginal  
effects when you've used bootstrapping to construct standard errors,  
but -mfx- is having that type of trouble?
