cauchyerrorpost {LearnBayes}

Log posterior of median and log scale parameters for Cauchy sampling

Description

Computes the log posterior density of (M,log S) when a sample is taken from a Cauchy density with location M and scale S and a uniform prior distribution is taken on (M, log S)

Usage

cauchyerrorpost(theta,data)

Arguments

theta

vector of parameter values of M and log S

data

vector containing sample of observations

Value

value of the log posterior
