Optional Stopping with Bayes Factors: a categorization and extension of folklore results, with an application to invariant situations [PDF]

, 2020
It is often claimed that Bayesian methods, in particular Bayes factor methods for hypothesis testing, can deal with optional stopping. We first give an overview, using elementary probability theory, of three different mathematical meanings that various ...

Stochastic Consensus Algorithms over General Noisy Networks

SICE Journal of Control, Measurement, and System Integration, 2020
Stochastic consensus algorithms are considered for multi-agent systems over noisy unbalanced directed networks. The graph which represents a communication network of the system is assumed to contain a directed spanning tree, that is, a given digraph is ...

A fine grained heuristic to capture web navigation patterns [PDF]

, 2000
In previous work we have proposed a statistical model to capture the user behaviour when browsing the web. The user navigation information obtained from web logs is modelled as a hypertext probabilistic grammar (HPG) which is within the class of regular

Predicting Recurrent Venous Thromboembolism in Patients With Deep-Vein Thrombosis: Development and Internal Validation of a Potential New Prediction Model (Continu-8)

Frontiers in Cardiovascular Medicine, 2021
Background: Previous prediction models for recurrent thromboembolism (VTE) are often complicated to apply and have not been implemented widely.Aim: To develop and internally validate a potential new prediction model for recurrent VTE that can be used ...

Iteratively regularized Newton-type methods for general data misfit functionals and applications to Poisson data [PDF]

, 2012
We study Newton type methods for inverse problems described by nonlinear operator equations $F(u)=g$ in Banach spaces where the Newton equations $F'(u_n;u_{n+1}-u_n) = g-F(u_n)$ are regularized variationally using a general data misfit functional and a ...

Stopping rules for phase II studies [PDF]

British Journal of Clinical Pharmacology, 2001
This paper, the second in a series of three papers concerned with the statistical aspects of interim analyses in clinical trials, is concerned with stopping rules in phase II clinical trials. Phase II trials are generally small‐scale studies, and may include one or more experimental treatments with or without a control.

ENHANCEMENT OF ITERATIVE TURBO DECODING FOR HARQ SYSTEMS [PDF]

ICTACT Journal on Communication Technology, 2016
This paper presents a new method for stopping the iterative turbo decoding. First, a bit-level convergence test using the cross-entropy analyses is used to select non converged bits and establish a simple and effective stopping rule.

Dynamical Systems Gradient method for solving nonlinear equations with monotone operators

, 2008
A version of the Dynamical Systems Gradient Method for solving ill-posed nonlinear monotone operator equations is studied in this paper. A discrepancy principle is proposed and justified. A numerical experiment was carried out with the new stopping rule.
