cnNodeLoglik: Node Log-likelihood

Description

For a given data sample, the function calculates the log-likelihood of a node with respect to a specified parent set.

Usage

a catNetwork object

node

an integer or a list of integers, node indices in the data

data

a matrix or data.frame of categories

pert

an optional perturbation matrix or data.frame

softmode

a logical, turns on/off the soft quantization mode

klmode

a logical, use the negative KL-distance or the log-likelihood
