In 2004 the Dutch government instituted a workplace-smoking ban. This study focuses on differences in compliance over time and between occupational sectors, and describes the background variables.

National level smoke-free legislation is implemented to protect the public from exposure to second-hand tobacco smoke (SHS). The first aim of this study was to investigate how successful the smoke-free hospitality industry legislation in Ireland (March 2004), France (January 2008), the...

Mixed mode surveys are becoming increasingly common. This has led to calls for tests of the differences in response patterns between survey modes. In this article, we present an analysis of mode effects, using data from Wave 1 of the ITC Netherlands Survey, conducted by web (CAWI) and telephone...

Bayesian optimal designs for binary longitudinal responses analyzed with mixed logistic regression describing a linear time effect are considered. In order to find the optimal number and allocations of time points, for different priors, cost constraints and covariance structures of the random...

Optimal design problems for logistic mixed effects models for binary longitudinal responses are considered. A function of the approximate information matrix under the framework of the Penalized Quasi Likelihood (PQL) and a generalized linear mixed model with autocorrelation is optimized. Locally...

Customarily, the choice between one- or two-colour microarray platforms is based on their respective practical and technical merits, contingent on objectives and constraints of the study at stake. Statistical efficiency, if accounted for, plays a secondary role. A cost-efficiency comparison of...
