WebbIn statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values.. The more inferences are made, the more likely erroneous inferences become. Several statistical techniques have been … WebbThe p value for the hazard ratio of progression free survival is reported as 0.009 in the paper. Even though it's statistical significant, but since the median survival time for patients with control regimen is in fact longer than that with experimental regimen, 12 months versus 8 months.

F t n − 1 (·) denotes the CDF of Student’s t distribution with n – 1 degrees of freedom. In the Bayesian paradigm, for notational simplicity, we let ν = 2 σ 2 and model the joint posterior distribution of θ and ν .
