Evaluation of overall treatment effect in MMRM Universiteit Hasselt
In longitudinal clinical trials for drug development, the study objective is often to evaluate overall treatment effect across all visits. Despite careful planning and study conduct, the occurrence of incomplete data cannot be completely eliminated. As a direct likelihood method, the mixed-effects model for repeated measures (MMRM) has become one of the preferred approaches for handling missing data in such designs. MMRM is a full multivariate ...
An evaluation of the traffic safety effect of fixed speed cameras Universiteit Hasselt KU Leuven
