many thanks! I was just asking for a r-square analogue, since the
students I will present the results to, might like to know, how the
measure of fit in an ordinal regression (e.g. the residual deviance)
compare to measures they know (from introductory courses to linear
regression) (such as the r-sq

First define the statistic you are interested in! There is an absolute
measure of fit, the residual devi
Hi
(1)In polr(), is there any way to calculate a pseudo analogue to the
R^2. Just for use as a purely descriptive statistic of the goodness of
fit?
(2) And: what are the assumptions which must be fulfilled, so that the
results of polr() (t-values, etc.) are valid? How can I test these
