PriorRatioPoisson {EDISON}

Calculate network prior ratio with Poisson prior.

Description

This function calculates the ratio of the Poisson prior for two networks.

Usage

PriorRatioPoisson(network.info, q, lambda)

Arguments

network.info

Network information collected using CollectNetworkInfo. Note that one needs to set network.info$new.nets.

q

Number of nodes in the network.

lambda

Vector of lambda hyperparameters for each network.

Value

Returns the ratio [prior of new network]/[prior of old network].
