loglikcushcov function

Log-likelihood function for a CUSH model with covariates

Compute the log-likelihood function for a CUSH model with covariates for the given ordinal responses.

loglikcushcov(m, ordinal, X, omega, shelter)

Arguments

• m: Number of ordinal categories
• ordinal: Vector of ordinal responses
• X: Matrix of selected covariates for explaining the shelter parameter
• omega: Vector of parameters for explaining the shelter effect, with length equal to NCOL(X)+1 to account for an intercept term (first entry of omega)
• shelter: Category corresponding to the shelter choice
