The Decentralized Wald Problem
Two detectors making independent observations must decide which one of two hypotheses is true. The decisions are coupled through a common cost function. It is shown that the detectors’ optimal decisions are characterized by thresholds which are coupled and whose computation requires the solution of two coupled sets of dynamic programming equations. An approximate computation of the thresholds i...
متن کاملAbraham Wald
This paper grew out of a lecture presented at the 54th Session of the International Statistical Institute in Berlin, August 13 20, 2003, Schneeweiss (2003). It intends not only to outline the eventful life of Abraham Wald (1902 1950) in Austria and in the United States but also to present his extensive scientific work. In particular, the two main subjects, where he earned most of his fame, are ...
متن کاملBiochemistry: Wald and Brown
(P being the pulsation period) could, therefore, assume any value. Moreover, if the disturbing force were periodic, a resonance of the free and forced periods would be immediately established and the amplitude of the oscillation greatly enhanced. Second-order effects, ignored in the present investigation, would thus probably soon become appreciable and could operate to destroy the resonance. Sh...
متن کاملThe Geometry of the Wald Test
The issue of the non-invariance of the Wald test under nonlinear reparametrisations of the restrictions under test is studied from a differential geometric viewpoint. Quantities that can be defined in purely geometrical terms are by construction invariant under reparametrisation, and various attempts are made to construct a Wald test out of such invariant quantities only. Despite the existence ...
متن کاملTowards Machine Wald
The past century has seen a steady increase in the need of estimating and predicting complex systems and making (possibly critical) decisions with limited information. Although computers have made possible the numerical evaluation of sophisticated statistical models, these models are still designed by humans because there is currently no known recipe or algorithm for dividing the design of a st...
