variable (take value 1-5). I would like to fit an ordered probit or ordered
logit but i didn't find a command or package who make that. Does anyone know
if it's exists ?
Try polr() from the MASS package (part of the standard install, also available
from r-project.org)
Or try vglm() from Thomas Yee's VGAM package (in beta, available from
Yee's web page, which you can find by googling Yee and VGAM)
