Statistics-Distributions-GTest version 0.1.2
The G-test of independence is an alternative to the chi-square test of independence for testing for independence in
contingency tables. G-tests are coming into increasing use and as with the chi-square test for independence the G-test
for independence is used when you have two nominal variables each with two or more possible values. The null hypothesis
is that the relative proportions of one variable are independent of the second variable. This module implements two two
equivalent, but marginally different approaches to calculate G scores (that described in
http://en.wikipedia.org/wiki/G-test and that used by http://udel.edu/~mcdonald/statgtestind.html). Benchmarking
indicates that first approach works about a third faster than the alternative. However, this difference
diminishes as the categories increase. See http://en.wikipedia.org/wiki/G-test and
http://udel.edu/~mcdonald/statgtestind.html.
