probcube function

Probability distribution of a CUBE model without covariates

Compute the probability distribution of a CUBE model without covariates.

probcube(m,pai,csi,phi)

Arguments

• m: Number of ordinal categories
• pai: Uncertainty parameter
• csi: Feeling parameter
• phi: Overdispersion parameter

Returns

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

Examples

m<-9
pai<-0.3
csi<-0.8
phi<-0.1
pr<-probcube(m,pai,csi,phi)
plot(1:m,pr,type="h", main="CUBE probability distribution",xlab="Ordinal categories")
points(1:m,pr,pch=19)
