Quantum Simpsons Paradox and High Order Bell-Tsirelson Inequalities
The well-known Simpson’s Paradox, or Yule-Simpson Effect, in statistics is often illustrated by the following thought experiment: A drug may be found in a trial to increase the survival rate for both men and women, but decrease the rate for all the subjects as a whole. This paradoxical reversal effect has been found in numerous datasets across many disciplines, and is now included in most intro...
متن کاملA Regression Paradox for Linear Models: Sufficient Conditions and Relation to Simpsons Paradox
An analysis of customer survey data using direct and reverse linear regression leads to inconsistent conclusions with respect to the effect of a group variable. This counterintuitive phenomenon, called the “regression paradox,” causes seemingly contradictory group effects when the predictor and regressand are interchanged. Using analytical developments as well as geometric arguments, we describ...
متن کاملParadox and Relativism
Since the time of Plato, relativism has been attacked as a self-refuting theory. Today, there are two basic kinds of argument that are used to show that global relativism is logically incoherent: first, a direct descendent of the argument Plato uses against Protagoras, called the peritrope; and, second, a more recent argument that relativism leads to an infinite regress. Although some relativis...

This paper deals both with the issues of confounding and of control, as the definition of a confounding factor is far from universal and there exist different methodological approaches, ex ante and ex post, for controlling for a confounding factor. In the first section the paper compares some definitions of a confounder given in the demographic and epidemiological literature with the definition...
