CUB (version 1.1.5)

probcubshe2: probcubshe2

Description

Probability distribution of a CUB model with explicit shelter effect

Usage

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

Value

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

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 \(\delta\).
