cnFind-method: Find Network by Complexity

Description

This is a model selection routine that finds a network in a set of networks for a given complexity.

Usage

cnFind(object, complexity = 0, alpha=0, factor=1)
 cnFindKL(object, numsamples)

Value

A catNetwork object.

Arguments

object

catNetworkEvaluate or list of catNetworks

complexity

an integer, target complexity

alpha

a character or numeric

factor

a numeric

numsamples

an integer

Author

N. Balov, P. Salzman

Details

The complexity must be at least the number of nodes of the networks. If no network with the requested complexity exists in the list, then the one with the closest complexity is returned. Alternatively, one can apply some standard model selection with alpha="BIC" and alpha=AIC.
