Webb21 apr. 2024 · In this setting model-based approaches are more attractive, but put stronger requirements on correct model specification. As expected, the results of the simulation study showed that the weighting approach (HT) performed poorly across a wide range of scenarios, despite a simplified scenario where uncorrelated variables were excluded.
