Selection of Variables and Functional Forms in Multivariable Analysis
Aim
Derive guidance for variable and function selection in multivariable analysis.
Focus
The main focus of TG2 is to identify influential variables and gain insight into their individual and joint relationship with the outcome. Two of the (interrelated) main challenges are selection of variables for inclusion in a multivariable explanatory model, and choice of the functional forms for continuous variables
