COST AND ACCURACY COMPARISONS IN MEDICAL TESTING USING SEQUENTIAL TESTING STRATEGIES
The practice of sequential testing is followed by the evaluation of accuracy, but often not by the evaluation of cost. This research described and compared three sequential testing strategies: believe the negative (BN), believe the positive (BP) and believe the extreme (BE), the latter being a …

Inference and Estimation in Change Point Models for Censored Data
… <p>In this dissertation, we first propose a sequential testing approach for detecting multiple change points in the Weibull accelerated failure time model, since this is sufficiently flexible to accommodate increasing, decreasing, or constant hazard rates and is also the only continuous …

Design and Monitoring of Clinical Trials with Clustered Time-to-Event Endpoint
… In addition, we prove that in group sequentially monitored cluster randomization studies, the log-rank statistics does not have independent increment property, which is different from the result for independent survival data. We further derive the limiting distribution of sequentially …

Adaptive Estimation and Detection Techniques with Applications
… is developed based on the VSMM. It can handle sequential failures and multiple failures by sensors or actuators. Fault detection and target maneuver detection can be formulated as change-point detection problems in statistics. It is of great importance to have the quickest detection of such …

Sharpening the Boundaries of the Sequential Probability Ratio Test
… thesis, we present an introduction to Wald’s Sequential Probability Ratio Test (SPRT) for binary outcomes. Previous researchers have investigated ways to modify the stopping boundaries that reduce the expected sample size for the test. In this research, we investigate ways to further improve …

SEQUENTIAL METHODS FOR NON-PARAMETRIC HYPOTHESIS TESTING
… is to develop such algorithms for two-sided sequential binary hypothesis testing.</p> <p>In this dissertation, we propose two algorithms for sequential non-parametric hypothesis testing. The proposed algorithms are based on the random distortion testing (RDT) framework. The RDT framework …

Learning-based Decision Making in Wireless Communications
… study deep reinforcement learning based active sequential testing for anomaly detection. We assume that there is an unknown number of abnormal processes at a time and the agent can only check with one sensor in each sampling step. To maximize the confidence level of the decision and minimize the …

Early Detection of Treatment's Side Effects: A Sequential Approach
… vaccination campaign, we developed an optimal sequential test that allows for the early detection of potential side effect(s). This test employs a rule to stop the vaccination process once the observed number of side effect incidents exceeds a certain (pre-determined) threshold. The optimality of …
