Fully conditional specification in multivariate imputation

S. van Buuren, +3 more
- 01 Dec 2006 - 
TL;DR: In this article, the authors investigated the performance of conditional model specification for multivariate imputation in incomplete multivariate data by means of simulation and showed that the results were produced using only five Gibbs iterations starting from a simple draw from observed marginal distributions.
Journal ArticleDOI

Systematic review of the effect of robot-aided therapy on recovery of the hemiparetic arm after stroke.

Grada Berendina Prange, +4 more
- 01 Mar 2006 - 
TL;DR: It is found that robot-aided therapy of the proximal upper limb improves short- and long-term motor control of the paretic shoulder and elbow in subacute and chronic patients; however, it is found no consistent influence on functional abilities.
Journal ArticleDOI

Time-varying covariates and coefficients in Cox regression models

Zhongheng Zhang, +4 more
- 21 Mar 2018 - 
TL;DR: This article aims to illustrate how to carry out statistical analyses in the presence of time-varying covariates or coefficients with R when the proportional hazards assumption of the Cox regression model does not hold.
Journal ArticleDOI

Helmet therapy in infants with positional skull deformation: randomised controlled trial

Renske van Wijk, +5 more
- 01 May 2014 - 
TL;DR: Based on the equal effectiveness of helmet therapy and skull deformation following its natural course, high prevalence of side effects, and high costs associated with helmet therapy, the use of a helmet as a standard treatment for healthy infants with moderate to severe skulls deformation is discouraged.
