Generalized Likelihood Ratio Statistics and Uncertainty Adjustments in Efficient Adaptive Design of Clinical Trials
Jay Bartroff, Tze Leung Lai
A new approach to adaptive design of clinical trials is proposed in a general multiparameter exponential family setting, based on generalized likelihood ratio statistics and optima…
Optimal Multistage Sampling in a Boundary-Crossing Problem
Jay Bartroff
Brownian motion with known positive drift is sampled in stages until it crosses a positive boundary . A family of multistage samplers that control the expected overshoot over th…
Asymptotically optimal multistage tests of simple hypotheses
Jay Bartroff
A family of variable stage size multistage tests of simple hypotheses is described, based on efficient multistage sampling procedures. Using a loss function that is a linear combin…
Efficient three-stage -tests
Jay Bartroff
Three-stage -tests of separated one-sided hypotheses are derived, extending Lorden's optimal three-stage tests for the one-dimensional exponential family by using Lai and Zhang'…
