Software
I am an active member of the R software community and was elected to the R Foundation for Statistical Computing.
R Package Development
- FactoMineR: Exploratory data analysis (PCA, MCA, multi-table analysis, etc.).
- missMDA: Imputation (matrix completion) for continuous/categorical data and PCA with missing values.
- denoiseR: Low-rank matrix estimation using regularized SVD and bootstrap.
My students have also developed packages linked to our work:
- misaem: Logistic regression with missing values.
- mimi: Generalized low-rank models for mixed/incomplete data.
- lori: Contingency tables with missing values and covariates.
- AdaptiveConformal: Adaptive conformal prediction for time series.
For causal inference with missing values, see grf and pipelines comparing estimators (IPW, AIPW, etc.).
Software Projects
- R-mis-static: [paper] A static website providing resources on missing data (lectures, workflows, tutorials). Contributions welcome!
- Causal Inference Taskview: Organizes R packages related to causal inference.
ICUBAM Development
I contributed to ICUBAM, an open-source tool for real-time visualization of ICU bed availability. Launched during the COVID-19 crisis, it aids ICU teams in managing patient flows, anticipating bed needs, and organizing transfers. Deployed in 130 ICUs across 40 départements, ICUBAM supports over 2,000 beds. Slides, Models, Paper, GitHub.
