Coincidence is the effect of quantifying the degree to which two events are said to be uncorrelated in causality. Many real effects are often dismissed as just a coincidence, when really there is a possibly hidden or unrealized link between the two.
Coincidence can be expressed as a raw probability or as an adjusted quantity, which is measured in Stans ():
