mecor: An R package for measurement error correction in linear regression models with a continuous outcome

no code implementations9 Feb 2021 Linda Nab, Maarten van Smeden, Ruth H. Keogh, Rolf H. H. Groenwold

In the package mecor, regression calibration methods and a maximum likelihood method are implemented to correct for measurement error in a continuous covariate in regression analyses.

Comparing methods addressing multi-collinearity when developing prediction models

no code implementations5 Jan 2021 Artuur M. Leeuwenberg, Maarten van Smeden, Johannes A. Langendijk, Arjen van der Schaaf, Murielle E. Mauer, Karel G. M. Moons, Johannes B. Reitsma, Ewoud Schuit

When predictors in such models are highly collinear, unexpected or spurious predictor-outcome associations may occur, thereby potentially reducing face-validity and explainability of the prediction model.

Propensity score estimation using classification and regression trees in the presence of missing covariate data

no code implementations25 Jul 2018 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 score estimation.

Impact of predictor measurement heterogeneity across settings on performance of prediction models: a measurement error perspective

1 code implementation27 Jun 2018 Kim Luijken, Rolf H. H. Groenwold, Ben van Calster, Ewout W. Steyerberg, Maarten van Smeden

Although such heterogeneity in predictor measurement across derivation and validation samples is very common, the impact on the performance of prediction models at external validation is not well-studied.
