Abstract: hordered performs a Hausman-type specification test whether categories in a ologit or oprobit model can be joined or dropped. To this end it estimates another ologit/oprobit model with a collaped response variable, or without observations with response-to-be-dropped, and makes a hausman-type comparison of estimates for the new model with estimates for the original model, excluding the cut-points. For those with Stata v6 on an internet-accessible machine, install by typing .net cd http://www.fss.uu.nl/soc/iscore/stata/ then .net install hordered
