Log posterior of mean and precision for Binomial/beta exchangeable model

Description

Computes the log posterior density of mean and precision for a Binomial/beta exchangeable model

Usage

betabinexch0(theta,data)

Arguments

theta matrix of parameter values where each row represents a value of (eta, K)
data a matrix with columns y (counts) and n (sample sizes)

Value

vector of values of the log posterior where each value corresponds to each row of the parameters in theta

Examples

n=c(20,20,20,20,20)
y=c(1,4,3,6,10)
data=cbind(y,n)
par1=c(.1, 10)
par2=c(.2, 20)
theta=rbind(par1,par2)
