probcubshe2 {CUB}

probcubshe2

Description

Probability distribution of a CUB model with explicit shelter effect

Usage

probcubshe2(m,pai,csi,delta,shelter)

Arguments

m

Number of ordinal categories

pai

Uncertainty parameter

csi

Feeling parameter

delta

Shelter parameter

shelter

Category corresponding to the shelter choice

Details

A CUB model with explicit shelter effect is a mixture of two components: a CUB distribution with uncertainty parameter \pi and feeling parameter \xi, and a degenerate distribution with unit mass at the shelter category (shelter) with mixing coefficient specified by \delta.

Value

The vector of the probability distribution of a CUB model with explicit shelter effect.
