polr (MASS) and lrm (Design) differences in tests of statistical signifcance
...these signif tests. So far, I understand the t is based on the
asymptotic Normality of the estimate of b, and for finite samples b/se
is not exactly distributed as a t. But I also had the impression that
the Wald value was an approximation as well.
