1/(B+1) is the significance level of the Monte Carlo test if the data give the most extreme value. (E.g. Ripley, 1987, p. 171.) This is a calculation, not a convention, and assumes a continuously distributed statistic. On Mon, 8 Mar 2004, Spencer Graves wrote: What is the standard

What is the standard convention for a Monte Carlo p-value when the observed outcome is more extreme than all simulations? The example provided by Cédric Fine produced a Monte Carlo p-value, according to Kjetil Halvorsen, of 2.2e-16 (based on 2000 replicates). This seems inappropriate to
