probihg function

Probability distribution of an IHG model

Compute the probability distribution of an IHG model (Inverse Hypergeometric) without covariates.

probihg(m,theta)

Arguments

• m: Number of ordinal categories
• theta: Preference parameter

Returns

The vector of the probability distribution of an IHG model.

Examples

m<-10
theta<-0.30
pr<-probihg(m,theta)
plot(1:m,pr,type="h",xlab="Ordinal categories")
points(1:m,pr,pch=19)
