CalculatePriorRatio {EDISON}  R Documentation 
This function calculates the ratio of the network structure priors for a structure move.
CalculatePriorRatio(method, q, lambda, network.info)
method 
Indicates which prior to use: 
q 
Number of nodes in the network. 
lambda 
Vector of lambda hyperparameter values for each network (needed for the Poisson prior). 
network.info 
The network information collected using

Returns the ratio of the network structure priors for the proposed structure move.
