DS.posterior.reduce: Posterior Expectation and Modes of DS object

Description

A function that determines the posterior expectations $E({\theta }_0|y_0)$ and posterior modes for a set of observed data.

Usage

DS.posterior.reduce(DS.GF.obj, exposure)

Arguments

DS.GF.obj

Object resulting from running DS.prior function on a data set.

exposure

In the case of the Poisson family with exposure, represents the exposure values for the count data.

Value

Returns $k\times 4$ matrix with the columns indicating PEB mean, DS mean, PEB mode, and DS modes for $k$ observations in the data set.
