Calculates predicted probabilities from models of class polr from a
model object and a vector of coefficient values. This is an auxiliary
function used in pre if sim=TRUE.
simPredpolr(object, coefs, n.coef)An object of class polr.
A vector of coefficients where elements 1 to n.coef give
model coefficients and elements n.coef+1 to k have intercepts.
Number of coefficients (minus intercepts) for the polr
model.
An n x m-category matrix of predicted probabilities
