Finite-sample bounds to the normal limit under group sequential sampling
Julian Aronowitz, Jay Bartroff
In group sequential analysis, data is collected and analyzed in batches until pre-defined stopping criteria are met. Inference in the parametric setup typically relies on the limit…
A New Characterization of Elfving's Method for High Dimensional Computation
Jay Bartroff
We give a new characterization of Elfving's (1952) method for computing c-optimal designs in k dimensions which gives explicit formulae for the k unknown optimal weights and k unkn…
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'…
