The expectation maximisation (EM) algorithm has proven to be e ective for a range of identi cation problems. Unfortunately, the way in which the EM algorithm has previously been applied has proven unsuitable for the commonly employed innovations form model structure. This paper addresses this problem, and presents a previously unexamined method of EM algorithm employment. The results are pro le...

Background In Ethiopia, improvement and innovation of the emergency care system is hindered by lack of specialist doctors trained in emergency medicine, underdeveloped emergency care infrastructure, and resource limitations. Our aim was to examine the critical factors affecting retention of graduates from the Addis Ababa University (AAU) post-graduate emergency medicine (EM) training program wi...

BACKGROUND Early mobilization (EM) of patients on mechanical ventilation (MV) is shown to improve outcomes after critical illness. Little is known regarding clinician knowledge of EM or multi-disciplinary barriers to use of EM in the intensive care unit (ICU). The goal of this study was to assess clinician knowledge regarding EM and identify barriers to its provision. METHODS Simultaneous cro...

This paper is concerned with the parameter estimation of a relatively general class of nonlinear dynamic systems. A Maximum Likelihood (ML) framework is employed in the interests of statistical efficiency, and it is illustrated how an Expectation Maximisation (EM) algorithm may be used to compute these ML estimates. An essential ingredient is the employment of so-called “particle smoothing” met...

A common problem in predictive validity studies in the educational and psychological fields, e.g. in educational and employment selection, is restriction in range of the predictor variables. There are several methods for correcting correlations for restriction of range. The aim of this paper was to examine the usefulness of two approaches to correcting for range restriction; Thorndike’s case 2 ...

In the paper, the effects of the Job Corps training program on employment and wages are evaluated, using data from a randomized study, the National Job Corps Study, and the principal stratification approach to simultaneously address the issues of noncompliance, truncation of wages by nonemployment, and missing outcomes. We conduct a likelihood-based analysis, proposing different ways of improvi...

The first ever human vs. computer no-limit Texas hold ’em competition took place from April 24– May 8, 2015 at River’s Casino in Pittsburgh, PA. In this article I present my thoughts on the competition design, agent architecture, and lessons learned.
