R: Calculates the ratio of an exponential hyperparameter move.

ExpHyperRatioTarget {EDISON}

R Documentation

Calculates the ratio of an exponential hyperparameter move.

Description

This function calculates the acceptance ratio of a level-1 hyperparameter move for a given target node.

Usage

ExpHyperRatioTarget(beta.proposed, beta.old, target.net, self.loops)

Arguments

`beta.proposed`	Proposed new hyperparameter value.
`beta.old`	Previous value of hyperparameter beta.
`target.net`	Network segments for the target node associated with this hyperparameter value.
`self.loops`	`'TRUE'` if self-loops are acceptable, `'FALSE'` otherwise.

Value

Returns the ratio of the exponential prior with the previous hyperparameter value and the proposed new hyperparameter value.
