Look elsewhere effect
Web15 de out. de 2010 · When searching for a new resonance somewhere in a possible mass range, the significance of observing a local excess of events must take into account the probability of observing such an excess anywhere in the range. This is the so called “look elsewhere effect”. http://philsci-archive.pitt.edu/10791/4/(PhilSci_online_first_version_26.06.2014)Higgs_and_Look_Elsewhere_Effect.pdf

WebThe look-elsewhere effect (sometimes referred to as LEE) is a cognitive bias that occurs in the statistical analysis of scientific experiments, particularly in the study of complex … WebThe only thing that can be estimated with some certainty is the look elsewhere effect within a given, well-defined analytical problem. Indeed Monte Carlo simulations are the method of choice. For example, if you have a number of bins in your binned data, you can evaluate how that changes the true (global) probability of observing a 3-sigma excess in any one …
