Acerca de

This skill equips Claude with specialized expertise in clinical trial methodology using R. It covers the entire trial lifecycle—from sample size calculation and randomization strategies (simple, stratified, minimization) to advanced analysis techniques like Group Sequential Designs, multiplicity adjustments, and MMRM for missing data. It facilitates regulatory compliance by incorporating ICH E9 estimand frameworks and CONSORT diagram generation, making it an essential tool for biostatisticians and clinical data scientists working with the Tidyverse and specialized R packages like gsDesign, rpact, and mmrm.
