Description

Kruschke, J. (2014). Doing Bayesian data analysis: A tutorial introduction with R, 2nd Ed. Academic Press.

Usage

HDIofGrid(probMassVec, credMass = 0.95)

Arguments

probMassVec	is a vector of probability masses at each grid point.
credMass	is the desired mass of the HDI region.

Value

value: A list with components: indices is a vector of indices that are in the HDI mass is the total mass of the included indices height is the smallest component probability mass in the HDI

Examples

For determining HDI of a beta(30,12) distribution
approximated on a grid:
  probDensityVec = dbeta( seq(0,1,length=201) , 30 , 12 )
 probMassVec = probDensityVec / sum( probDensityVec )
  HDIinfo = HDIofGrid( probMassVec )
  show( HDIinfo )
