Description

This is a function for comparing two sets of texts; unlike keywords analysis, it this method the goal is to split input texts into equal-sized slices, and to check the appearance of particular words over the slices. Number of slices in which a given word appeared in the subcorpus A and B is then compared using standard chisquare test (if p value exceeds 0.05, a difference is considered significant). This method is based on original Zeta as developed by Burrows and extended by Craig (Burrows 2007, Craig and Kinney 2009).

Usage

1
zeta.chisquare(input.data)

Arguments

input.data

a matrix of two columns.

Value

The function returns a list of two elements: the first contains words (or other units, like n-grams) statistically preferred by the authors of the primary subcorpus, while the second element contains avoided words. Since the applied measure is symmetrical, the preferred words are ipso facto avoided by the secondary authors, and vice versa.
