Abstract:
|
P-values are frequently misused and misunderstood as evidence. The sample to sample variability of p-values and the effects of multiple testing (explicit or implicit) are seldom appreciated by scientists using p-values to summarize their studies. In this talk I discuss some of the important features of the sampling distribution of p-values under continuous and discrete testing. I will also share some ideas of how the concept of false discovery rate can assist in calibrating p-values for better interpretability.
