Bayesian stopping rules for trials

The Lancet, 2002
Laparoscopic surgery carries the risk of serious bile-duct damage, although there is a good evidence that, the incidence of biliary injury can be reduced to a rate comparable to that of open cholecystectomy. Oral bileacid dissolution therapy, contact solvent dissolution, or mechanical extraction through a catheter placed into the gallbladder ...

Special Topic: Optimal Stopping Rules

2021
Optimal stopping rules are developed to maximize a reward or minimize a loss in a martingale framework by stopping the process at the right time. Applications include the pricing of American options and the “search for the best” (secretary problem) algorithm.

Sequential stopping rules in clinical trials

Statistics in Medicine, 1990
AbstractThis paper reviews aspects of the development of sequential analysis of clinical trial data in medicine and suggests simple strategies for progress. The emphasis is on the pragmatic and ethical requirements of aspects of the design of phase III trials and in circumstances of genuine uncertainty characterized by much clinical experimentation. In

Stopping Rules for Stochastic Decomposition

1996
In our development thus far, we have concentrated on objective function approximations within a Stochastic Decomposition algorithm and on establishing asymptotic optimality of the solutions provided by SD. While such asymptotic properties provide the necessary analytic foundation for the algorithm, any practical computer implementation requires ...

Stopping Rules For Trials

1996
The duration of treatment for the individual patient is specified at the design stage as is the total number of subjects to enter the trial. In the normal course of events the trial will last as long as it takes to enter the required number of patients and for the last patient to complete the study.

Stopping Rules in Political Settings

2021
This chapter compares three rules of voice integration or ‘stopping rules’ (majority voting, unanimity, consensus) in terms of their democratic, epistemic and pragmatic value. It shows, first, how the consensus rule, whereby decisions are made without voting when nobody opposes openly, fares best at reconciling all three normative demands and, second ...

Ruling Out Light Stops

2016
Understanding the extent to which experimental searches are sensitive to scenarios involving Light Stops (LST) is essential to resolve questions about naturalness, electroweak baryo-genesis and Dark Matter. In this chapter, the reach on LST scenarios is characterised in two ways.
