Here we show that the one-sided chi-square test used for evaluating the significance of the overlap between the RH network and other existing datasets and the Bayesian loglikelihood score (LLS) approach used for integrating diverse datasets [1,2] are closely related. The Fisher’s exact test was used instead of the chi-square test when the expected value in a cell of the contingency table was ≤ ...

I investigate the use of Pearson’s chi-square statistic, the Maximum Likelihood Ratio statistic for Poisson distributions, and the chi-square-gamma statistic (Mighell 1999, ApJ, 518, 380) for the determination of the goodness-of-fit between theoretical models and low-count Poisson-distributed data. I demonstrate that these statistics should not be used to determine the goodness-of-fit with data...

This study was designed to compare the presence of seven clinical signs in a group of patients with migraine with that of patients with non-migraine headache. Migraine is sometimes misdiagnosed. Therefore additional features are useful to improve the diagnostic accuracy of migraine. A cross sectional descriptive study was conducted in a group of 709 outpatients with headache. The physical signs...
