Seminar selection of variables and functional forms for multivariable models (11:00-12:00)
After a very short introduction of the STRATOS initiative and its main aims, Georg Heinze will concentrate on issues of variable and functional form selection for multivariable models. In multivariable model building, the gap between cutting-edge methodology and daily practice of data analysis is large. For example, according to recent systematic reviews, univariate screening of variables considered for multivariable models is still common practice and sometimes even believed to be a precondition for inclusion. Furthermore, while there are sophisticated and well-investigated methods for considering nonlinear functional forms of continuous variables in such models, dichotomization of such variables is still popular. If continuous variables are not dichotomized, the linearity assumption is often not questioned. We give an overview of methods for selection of variables and functional forms, discuss recommendations for practitioners and point at open gaps in research.
Masterclass in selection of variables and functional forms (13:00-15:00)
This 2-hours workshop will provide further insights in the selection of variables and functional forms for multivariable model building. The first part of the workshop will deal with the relative performance of various popular methods to select variables for multivariable model. In the second part of the workshop, different methods to deal with nonlinear functional forms of continuous variables in multivariable models will be dealt with.
