m |
Number of ordinal categories |

A CUB model with explicit shelter effect is a mixture of two components:
a CUB distribution with uncertainty parameter π and feeling parameter ξ,
and a degenerate distribution with unit mass at the shelter category (shelter
)
with mixing coefficient specified by δ.
The vector of the probability distribution of a CUB model with explicit shelter effect.
