auxmat: Auxiliary matrix

In CUB: A Class of Mixture Models for Ordinal Data

Description

Returns an auxiliary matrix needed for computing the variance-covariance matrix of a CUBE model with covariates.

Usage

Arguments

m	Number of ordinal categories
vettcsi	Vector of the feeling parameters of the Beta-Binomial distribution, with length equal to the number of observations
