Plot Intercepts
Description
Plots the step function corresponding to the intercepts in a orm
or lrm
model. This can be thought
of as the link function of the covariate-adjusted empirical cumulative distribution function
(actually 1 - ECDF). It is
also related to q-q plots. For example, if a probit link function is an appropriate choice, and the
residuals actually had a normal distribution (not needed by the semiparametric ordinal model), the step
function of the intercepts would form a straight line.
