Have you had a look at the intros to -ologit- and -oprobit- in the [R]
manual, pp. 1268 and 1291 yet? They do not mention equally spaced levels as
a condition for their use...

Subject: st: Nominal or ordinal?

Dear Statalisters,

I am working with a dependent variable that has the following four potential
responses: (1) Not Likely, (2) Slightly Likely, 
(3) Quite Likely, (4) Extremely Likely.

A colleague thinks this is an ordinal variable which should be analyzed
using ordered logit regression.  My sense was that 
this is a nominal variable, and should be analyzed using multinomial
regression - since we cannot know if the levels are 
equally spaced in people's minds.

My apologies for what is probably a very simplistic question, but I've
searched Statalist and online, and I still am not 
entirely certain.  I would greatly appreciate input on this question.
