Description
1. Implementation of GTest (LogLikelihood ratio LLR test for independence and goodnesoffit)
2. Reference: http://en.wikipedia.org/wiki/Gtest
3. ReasonsUsefulness: Gtests are tests are increasingly being used in situations where chisquared tests were previously recommended.
The approximation to the theoretical chisquared distribution for the Gtest is better than for the Pearson chisquared tests. In cases where Observed >2*Expected for some cell case, the Gtest is always better than the chisquared test.
For testing goodnessoffit the Gtest is infinitely more efficient than the chi squared test in the sense of Bahadur, but the two tests are equally efficient in the sense of Pitman or in the sense of Hodge and Lehman.
