Auxiliary function for the log-likelihood estimation of IHG models with covariates

Description

Compute the opposite of the log-likelihood function for an IHG model with covariates for the preference parameter.

Usage

effeihgcov(nu, ordinal, U, m)

Arguments

nu

Vector of the starting values for the parameters to be estimated, with length equal to NCOL(U)+1 to account for an intercept term (first entry of nu)

ordinal

Vector of ordinal responses

U

Matrix of the explanatory variables for the preference parameter \theta

m

Number of ordinal categories

Details

It is called as an argument for "optim" within IHG function (with covariates) as the function to minimize.
