The Box-Cox power exponential (BCPE) distribution, developed in this paper, provides a model for a dependent variable Y exhibiting both skewness and kurtosis (leptokurtosis or platykurtosis). The distribution is defined by a power transformation Y(nu) having a shifted and scaled (truncated) standard power exponential distribution with parameter tau. The(More)
A variety of methods of modelling overdispersed count data are compared. The methods are classified into three main categories. The first category are ad hoc methods (i.e. pseudo-likelihood, (extended) quasi-likelihood, double exponential family distributions). The second category are discretized continuous distributions and the third category are(More)
The aim of this study was to provide normative data for performance on the 20 m shuttle-run test of cardiorespiratory fitness in English schoolchildren. A total of 7366 10-16 year olds completed the 20 m shuttle-run test. We expressed performance as the number of shuttles completed, test score (shuttles and levels) and estimated peak oxygen consumption(More)
BACKGROUND Ankle sprains are the most common form of acute injury in volleyball. A prevention programme consisting of technical training, proprioceptive training, and external support was previously designed to reduce the rate of ankle sprains in volleyball players. OBJECTIVE To investigate which of these three interventions is the most effective in(More)
Tennis elbow or lateral epicondylitis is one of the most common lesions of the arm with a well defined clinical presentation, which significantly impacts on the community. Many treatment approaches have been proposed to manage this condition. One is Cyriax physiotherapy. The effectiveness and reported effects of this intervention are reviewed.
A plethora of terms that have been used to describe lateral epicondylitis including tennis elbow (TE), epicondylalgia, tendonitis, tendinosis and tendinopathy. These terms usually have the prefix extensor or lateral elbow. Lateral elbow tendinopathy seems to be the most appropriate term to use in clinical practice because other terms make reference to(More)
OBJECTIVE To derive regional weight-for-age growth references to help optimize age-based dosing of antimalarials in Africa, the Americas, South-East Asia and the Western Pacific. METHODS A weight-for-age database was constructed from pre-existing population-based anthropometric data obtained from household surveys and research groups. It contained data(More)
An important assumption in many linear mixed models is that the conditional distribution of the response variable is normal. This assumption is violated when the models are fitted to an outcome variable that counts the number of correctly answered questions in a questionnaire. Examples include investigations of cognitive decline where models are fitted to(More)
c We simulate the future scenario of crude oil export and production using ACEGES. c The simulated results are analyzed using the GAMLSS framework. c The peak points of oil export and production will come early in this century. c The OPCE Middle East will produce most of the world crude oil in the near future. c These countries will continuously be the key(More)
