In CUB: A Class of Mixture Models for Ordinal Data

Log-likelihood function of a CUB model without covariates

Usage

ellecub(m,ordinal,assepai,assecsi)

Arguments

m	Number of ordinal categories
ordinal	Vector of ordinal responses
assepai	Vector of uncertainty parameters for given observations (with the same length as ordinal)
assecsi	Vector of feeling parameters for given observations (with the same length as ordinal)
