A shortcut method is proposed using binomial coefficients to find the probabilities of all possible configurations of a 2 x 3 contingency table in a single operation. The method is especially useful ...

Importance sampling has been reported to produce algorithms with excellent empirical performance in counting problems. However, the theoretical support for its efficiency in these applications has ...

sorts the data in descending order so that the first table cell contains the frequency of positive exposure and positive response computes chi-square tests, exact Pearson chi-square test, and Fisher's ...
