rms (version 7.0-0)

plotIntercepts: 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.

Usage

plotIntercepts(fit)

Value

nothing; only plots

Arguments

fit

an orm or lrm fit object, usually with a numeric dependent variable having many levels
