I'm trying to compute the marginal effects for an ordered logit with nine dependent outcomes. Is there a way to group four of the outcomes (i.e. 0-4) and get the marginal effects and probability of being part of this group?

Thanks
The only way I know of to do it is by hand. Alternatively, have you considered just combining the categories in the first place before you run the ologit?

Alternatively, I suppose you might be able to work out something using Tamas Bartus's -margeff- command. If you use the -replace- option, the marginal effects get saved in e(b), and you could probably write a routine to add effects together from there.
