Measurement error in continuous endpoints in randomised trials: problems and solutions
Linda Nab, Rolf H. H. Groenwold, Paco M. J. Welsing +1
In randomised trials, continuous endpoints are often measured with some degree of error. This study explores the impact of ignoring measurement error, and proposes methods to impro…
Propensity score estimation using classification and regression trees in the presence of missing covariate data
Bas B. L. Penning de Vries, Maarten van Smeden, Rolf H. H. Groenwold
Data mining and machine learning techniques such as classification and regression trees (CART) represent a promising alternative to conventional logistic regression for propensity…
Impact of predictor measurement heterogeneity across settings on performance of prediction models: a measurement error perspective
Kim Luijken, Rolf H. H. Groenwold, Ben van Calster +2
It is widely acknowledged that the predictive performance of clinical prediction models should be studied in patients that were not part of the data in which the model was derived.…
