cnFindAIC-method: Find Network by AIC

Description

This is a model selection routine that finds a network in a set of networks using the AIC criteria.

Usage

cnFindAIC(object, numsamples)

Value

A catNetwork object with optimal AIC value.

Arguments

object

A list of catNetwork objects or catNetworkEvaluate

numsamples

an integer

Author

N. Balov, P. Salzman

Details

The function returns the network with maximal AIC value from a list of networks as obtained from one of the search-functions cnSearchOrder, cnSearchSA and cnSearchSAcluster. The formula used for the AIC is log(Likelihood) - Complexity.
