chiSquareTest {clickstream}

Calculates the chi-square statistic

Description

Calculates the chi-Square statistic, p-value, and degrees of freedom, for the first-order transition matrix of a MarkovChain object compared with observed state changes.

Usage

chiSquareTest(cls, mc)

Arguments

cls

The clickstream object.

mc

The Markov chain against which to compare the clickstream data. Please note that the first-order transition matrix is used for performing the chi-square test.
