DiffMeansPermute Limitations #102

Closed gmrwvu closed 6 years ago

gmrwvu commented 6 years ago

I would like to clarify any distribution limitations for your DiffMeansPermute hypothesis class. This class computes its own distribution of the test statistic for two groups. So, the two groups can have a uniform, exponential, normal, or Pareto distribution and the resultant p-value would still indicate significance in the difference between the means. Am I understanding this correctly?

Yes, permutation tests do not make any distribution assumptions.
