cnLoglik-method: Sample Log-likelihood

Description

Calculate the log-likelihood of a sample with respect to a given catNetwork object

Usage

cnLoglik(object, data, bysample=FALSE)

Arguments

object

a catNetwork object

data

a data matrix given in the column-sample format, or a data.frame in the row-sample format

bysample

a logical

Value

• A numeric value

Details

If bysample is set to TRUE, the function output is a vector of length the sample size with values the log-likelihood of each individual sample instance. Otherwise, the total sum of the log-likelihood of the sample instances is reported.
