A Law of Likelihood for Composite Hypotheses
The law of likelihood underlies a general framework, known as the likelihood paradigm, for representing and interpreting statistical evidence. As stated, the law applies only to simple hypotheses, and there have been reservations about extending the law to composite hypotheses, despite their tremendous relevance in statistical applications. This paper proposes a generalization of the law of lik...
متن کاملSearching through composite time series
Recently there has been much interest in detecting anomalies in both categorical and real valued time series data. Many classical statistical methods deal with univariate data, and less has been done about multivariate data. The drastic decrease of data storage costs, availability of cheap sensors along with automation of systems have resulted in proliferation of time series data. In most cases...
متن کاملTesting Composite Hypotheses via Convex Duality ∗
We study the problem of testing composite hypotheses versus composite alternatives, using a convex duality approach. In contrast to classical results obtained by Krafft & Witting [11], where sufficient optimality conditions are obtained via Lagrange duality, we obtain necessary and sufficient optimality conditions via Fenchel duality under some compactness assumptions. This approach also differ...
متن کاملComposite Hypotheses and Generalized Likelihood Ratio Tests
In many real world problems, it is difficult to precisely specify probability distributions. Our models for data may involve unknown parameters or other characteristics. Here are a few motivating examples. Example: Unknown amplitudes/delays in wireless communications. We don't always know how many relays a signal will go through, how strong the signal will be at each receiver, the distance betw...
متن کاملTesting composite hypotheses about discrete ergodic processes
Given a discrete-valued sample X1, . . . ,Xn, we wish to decide whether it was generated by a distribution belonging to a family H0, or it was generated by a distribution belonging to a family H1. In this work we assume that all distributions are stationary ergodic and do not make any further assumptions (in particular, no independence or mixing rate assumptions). We find some necessary and som...
