probcush function

Probability distribution of a CUSH model

Compute the probability distribution of a CUSH model without covariates, that is a mixture of a degenerate random variable with mass at the shelter category and the Uniform distribution.

probcush(m,delta,shelter)

Arguments

• m: Number of ordinal categories
• delta: Shelter parameter
• shelter: Category corresponding to the shelter choice

Returns

The vector of the probability distribution of a CUSH model without covariates.

Examples

m<-10
shelter<-1
delta<-0.4
pr<-probcush(m,delta,shelter)
plot(1:m,pr,type="h",xlab="Number of categories")
points(1:m,pr,pch=19)
