Steven Abrams has recently been awarded his PhD in Statistics degree from Hasselt University. We are very happy that Steven will continue to be a member of the SIMID team. Steven Abrams: 'Statistical models for estimating individual heterogeneity in acquisition of infectious diseases and outbreak risk in highly vaccinated populations' - 18 September 2015.
Wim Delva has been awarded a postdoctoral fellowship by the FWO and will join the SIMID group. His FWO research project is a collaborative project between Hasselt University (Niel Hens) and the KULeuven (Annemie Vandamme), entitled "Combining phylodynamics and agent-based HIV transmission modelling to advance epidemiological methodology and evidence- based public health policies for HIV prevention and treatment"
Benson Ogunjimi and Lander Willem have recently been awarded their PhD degree.

We have proposed penalized generalized estimating equations with Elastic Net or L2-Smoothly Clipped Absolute Deviation penalization to simultaneously select the most important variables and estimate their effects for longitudinal Gaussian data when multicollinearity is present. The method is able to consistently select and estimate the main effects even when strong correlations are present. In addition, the potential pitfall of time-dependent covariates is clarified.
