Description Details Slots Methods Author(s) See Also

This class contains a list of `catNetwork`

s together with some diagnostic metrics and information. `catNetworkEvaluate`

objects are created automatically as result of calling `cnEvaluate`

or one of the `cnSearch`

functions.

The class `catNetworkEvaluate`

is used to output the result of two functions: `cnEvaluate`

and `cnSearchSA`

.
The usage of it in the first case is explained next.
The complexity and log-likelihood of the networks listed in `nets`

slots are stored in
`complexity`

and `loglik`

slots.
Function `cnEvaluate`

and `cnCompare`

fills all the slots from `hamm`

to `markov.fn`

by comparing these networks with a given network.
See in the manual of `cnCompare`

function for description of different distance criteria.
By calling `cnPlot`

upon a `catNetworkEvaluate`

object, some relevant comparison information can be plotted.

When `catNetworkEvaluate`

is created by calling `cnSearchSA`

or `cnSearchSAcluster`

functions,
`complexity`

and `loglik`

contains the information not about the networks in the `nets`

list,
but about the optimal networks found during the stochastic search process.
Also, the slots from `hamm`

to `markov.fn`

are not used.
