Robust empirical calibration of p‐values using observational data

In our previous paper [1], we proposed empirical calibration of p-values as a strategy for mitigating risk of systematic error when estimating average treatment effects from observational studies. By estimating the effect of exposure on outcomes across a collection of settings where the exposure is not believed to cause the outcome (negative controls), one can estimate an empirical null distrib...

Interpreting observational studies: why empirical calibration is needed to correct p-values

Often the literature makes assertions of medical product effects on the basis of ' p < 0.05'. The underlying premise is that at this threshold, there is only a 5% probability that the observed effect would be seen by chance when in reality there is no effect. In observational studies, much more than in randomized trials, bias and confounding may undermine this premise. To test this premise, we ...

Calibration of p Values for Testing Precise Null Hypotheses

P values are the most commonly used tool to measure evidence against a hypothesis or hypothesized model. Unfortunately, they are often incorrectly viewed as an error probability for rejection of the hypothesis or, even worse, as the posterior probability that the hypothesis is true. The fact that these interpretations can be completely misleading when testing precise hypotheses is Ž rst reviewe...

Camera Calibration Technique using Robust

In this paper we present an algorithm for camera and projector calibration of the liquid crystal range nder using space encoding technique. Because the accuracy of calibration is aaected by noises, and the variation of position or scale of the reference object in the input images, the least-median-of-squares technique is used in our approach, instead of the conventional least squares method. Th...
