Robustness Evaluation in Sequential Testing of Composite Hypotheses
نویسنده
چکیده
The problem of sequential testing of composite hypotheses is considered. Asymptotic expansions are constructed for the conditional error probabilities and expected sample sizes under “contamination” of the probability distribution of observations. To obtain these results a new approach based on approximation of the generalized likelihood ratio statistic by a specially constructed Markov chain is proposed. The approach is illustrated numerically.

Analysis of Robustness for Sequential Tests of Composite Hypotheses under Functional Distortion of Priors and Likelihoods
Composite hypotheses are tested sequentially in many applications, especially in medicine and quality control (see Lai (2001)). Although some optimal properties of sequential tests are valid (see, for example, Malyutov et al. (2000)) in frames of hypothetical models, the observed data do not follow these models exactly, the hypothetical models are distorted (see Huber (2004) and Hampel et al. (...

Usual sequential testing procedures often are very sensitive against even small deviations from the ideal model underlying the hypothe ses This makes robust procedures highly desirable To rely on a clearly de ned optimality criterion we incorporate robustness aspects di rectly into the formulation of the hypotheses considering the problem of sequentially testing between two interval probabiliti...
متن کاملAR-order estimation by testing sets using the Modified Information Criterion
The Modified Information Criterion (MIC) is an Akaike-like criterion which allows performance control by means of a simple a priori defined parameter, the upper-bound on the error of the first kind (false alarm probability). The criterion MIC is for example used to estimate the order of Auto-Regressive (AR) processes. The criterion can only be used to test pairs of composite hypotheses; in an A...
متن کاملSub-optimal Nonparametric Hypotheses Discriminating with Guaranteed Decision
We study the problem of testing composite hypotheses versus composite alternatives when there is a slight deviation between the model and the real distribution. The used approach, which we called sub-optimal testing, implies an extension of the initial model and a modification of a sequential statistically significant test for the new model. The sub-optimal test is proposed and a non-asymptotic...
متن کاملOptimal Learning under Robustness and Time-Consistency
We model learning in a continuous-time Brownian setting where there is prior ambiguity. The associated model of preference values robustness and is timeconsistent. The model is applied to study optimal learning when the choice between actions can be postponed, at a per-unit-time cost, in order to observe a signal that provides information about an unknown parameter. The corresponding optimal st...
