Testing Exchangeability On-Line
The majority of theoretical work in machine learning is done under the assumption of exchangeability: essentially, it is assumed that the examples are generated from the same probability distribution independently. This paper is concerned with the problem of testing the exchangeability assumption in the on-line mode: examples are observed one by one and the goal is to monitor on-line the streng...
متن کاملExchangeability and regression models
Sir David Cox’s statistical career and his lifelong interest in the theory and application of stochastic processes began with problems in the wool industry. The problem of drafting a strand of wool yarn to near uniform width is not an auspicious starting point, but an impressive array of temporal and spectral methods from stationary time series were brought to bear on the problem in Cox (1949)....
متن کاملExchangeability, Representation Theorems, and Subjectivity
According to Bruno de Finetti’s Representation Theorem, exchangeable beliefs over infinite sequences of observable Bernoulli quantities can be represented as mixtures of independent coin tossing experiments. Extensions of this theorem give rise to representations as mixtures of other familiar sampling distributions. This paper offers a subjectivist primer based on the premise that appreciation ...
متن کاملIdentifiability, exchangeability, and epidemiological confounding.
Non-identifiability of parameters is a well-recognized problem in classical statistics, and Bayesian statisticians have long recognized the importance of exchangeability assumptions in making statistical inferences. A seemingly unrelated problem in epidemiology is that of confounding: bias in estimation of the effects of an exposure on disease risk, due to inherent differences in risk between e...
متن کاملIdentifiability, exchangeability and confounding revisited
In 1986 the International Journal of Epidemiology published "Identifiability, Exchangeability and Epidemiological Confounding". We review the article from the perspective of a quarter century after it was first drafted and relate it to subsequent developments on confounding, ignorability, and collapsibility.
