The paper introduces dGAMLSS, a distributed algorithm for fitting GAMLSS models to construct population reference charts without sharing patient data.

The paper introduces ODAC, a privacy-preserving distributed algorithm for multi-center Cox proportional hazard models, showing it matches pooled estimates and outperforms meta-analysis for rare events.

This study evaluates how phenotyping errors affect polygenic risk score (PRS) accuracy using eMERGE data, showing accuracy degradation depends on phenotype and error mechanism.
