In BayesianFROC: FROC Analysis by Bayesian Approaches

Description

Extract a name of parameter from StanfitExtended object (or stanfit object.)

Usage

name_of_param_whose_Rhat_is_maximal(StanS4class)

Arguments

StanS4class

An S4 object of class stanfitExtended which is an inherited class from the S4 class stanfit. This R object is a fitted model object as a return value of the function fit_Bayesian_FROC(). To be passed to DrawCurves() ... etc

Value

An object of class "character" indicating a parameter whose chain has the maximal R hat over all chains of MCMC parameters.
