This seems like a great tool for certain statistical applications. I am learning a bit about the controversey surrounding extremely small p-values in Genome Wide Association Studies (think a million n ANOVA) and machine precision. I guess tools like this would be very useful to make sure your statistical tests can more accurately calculate p-values approaching the limits of machine precision.
- contravariant 6y agoIf your p-values are approaching machine precision then you don't need better floating point precision you need to be using the log-likelihood (admittedly for gaussian samples this is the variance which requires some careful handling). Also if your p-values are approaching machine precision, then maybe p-values aren't the most meaningful metric.
