p-Value Histograms: Inference and Diagnostics

  • Patrick Breheny,
  • Arnold Stromberg and
  • Joshua Lambert

31 August 2018

It is increasingly common for experiments in biology and medicine to involve large numbers of hypothesis tests. A natural graphical method for visualizing these tests is to construct a histogram from the p-values of these tests. In this article, we e...

From p-Values to Posterior Probabilities of Null Hypotheses

  • Daiver Vélez Ramos,
  • Luis R. Pericchi Guerra and
  • María Eglée Pérez Hernández

6 April 2023

Minimum Bayes factors are commonly used to transform two-sided p-values to lower bounds on the posterior probability of the null hypothesis, in particular the bound −e·p·log(p). This bound is easy to compute and explain; however,...
