Webb22 feb. 2024 · Simpson’s paradox, also called Yule-Simpson effect, in statistics, an effect that occurs when the marginal association between two categorical variables is qualitatively different from the partial association between the same two variables after controlling for one or more other variables. Simpson’s paradox is important for three … WebbSimpson (1985) gives the following list of areas which can be analyzed by reverse mathematics: number theory, geometry, calculus, differential equations, real and complex anal- ysis, combinatorics, countable algebra, separable Banach spaces, computability theory, and the topologyof complete separable metric spaces.
Simpson's reversal can also arise in correlations, in which two variables appear to have (say) a positive correlation towards one another, when in fact they have a negative correlation, the reversal having been brought about by a "lurking" confounder. Berman et al. give an example from economics, where a dataset suggests overall demand is positively correlated with price (that is, higher prices lead to more demand), in contradiction of expectation.

This result is often encountered in social-science and medical-science statistics, [1] [2] [3] and is particularly problematic when frequency data are unduly given causal interpretations. [4]
