Description Usage Arguments Details See Also Examples

View source: R/probihgcovn.R

Description

Given a vector of n ratings over m categories, it returns a vector of length n whose i-th element is the probability of observing the i-th rating for the corresponding IHG model with parameter θ_i, obtained via logistic link with covariates and coefficients.

Usage

1
probihgcovn(m,ordinal,U,nu)

Arguments

m

Number of ordinal categories

ordinal

Vector of ordinal responses

U

Matrix of selected covariates for explaining the preference parameter

nu

Vector of coefficients for covariates, whose length equals NCOL(U)+1 to include an intercept term in the model (first entry)

Details

The matrix U is expanded with a vector with entries equal to 1 in the first column to include an intercept term in the model.
