Provides users the necessary utility functions to generate permutationbased QQ plots and also estimate inflation factor based on the empirical NULL distribution. While it has general utility, it is particularly helpful when the skewness of the Fisher's Exact test in sparse data situations with imbalanced casecontrol sample sizes renders the reliance on the uniform chisquare expected distribution inappropriate.
