R: Calculates the MH ratio of the binomial prior.

BinoHyperRatio {EDISON}

R Documentation

Calculates the MH ratio of the binomial prior.

Description

This function calculates the ratio of the binomial information sharing prior with the proposed new hyperparameter values, and the binomial prior with the current hyperparameter values.

Usage

BinoHyperRatio(params.proposed, changed, node.sharing, network.info)

Arguments

`params.proposed`	The new proposed hyperparameter values for the binomial prior.
`changed`	Gives the index of the parameter that has changed.
`node.sharing`	Type of information sharing among nodes: `'soft'` or `'hard'`.
`network.info`	The network information as collected by `CollectNetworkInfo`.

Value

This function returns a number greater than zero which represents the ratio of binomial priors.
