mederrRank (version 0.1.0)

mederrResample-class: Class "mederrResample". Simulated Monte Carlo Chains (Step 2) for the Bayesian Hierarchical Model Used to Identify the Most Harmful Medication Errors.

Description

This class encapsulates the information needed to resample the Monte Carlo chains for the Bayesian Hierarchical Model as described in Myers et al. (2011) using user defined values for \(k\) and \(eta\).

Arguments

Objects from the Class

Objects can be created by calls of the form new("mederrResample", log.ir, samp, A, t.new, t.old, grd), but most often as the result of a call to bhm.resample.

Slots

log.ir:

Object of class "array"; logarithm of the importance ratio for each pair of \((k,\eta)\) values.

samp:

Object of class "array"; resampled MCMC simulation indexes.

A:

Object of class "array"; transformation ratio for each pair of \((k,\eta)\) values.

t.new:

Object of class "array"; \(\theta_i\) posterior modes using \((k = \infty, \eta = 1)\).

t.old:

Object of class "numeric"; \(\theta_i\) posterior modes using user defined \((k, \eta)\) values.

grd:

Object of class "list"; grid of required \((k, \eta)\) values.

Methods

%\item{initialize}{\code{signature(.Object = "mederrResample")}: ... }
plot

signature(x = "mederrResample", y = "missing"): : Provides a graphical representation of a mederrResample object.
