ndlStatistics: Calculate goodness of fit statistics for a naive discriminative learning model.

Description

ndlStatistics takes an Naive Discriminary Learning model object as generated by ndlClassify and calculates a range of goodness of fit statistics using modelStatistics.

Usage

ndlStatistics(ndl, …)

Arguments

ndl

A naive discriminative learning model fitted with ndlClassify.

…

Control arguments to be passed along to modelStatistics.

Value

A list with the following components:

n.data

sum frequency of data points

df.null

degrees of freedom of the Null model

df.model

degrees of freedom of the fitted model

statistics
