Statistical tools and research software I have developed or contributed to, spanning clinical study design and reproducible inference.
pppower
Power and sample size planning
R tools for planning studies that use prediction-powered inference.
My contribution: Co-developed the R package, with modular functions, CI testing, documentation, and simulation studies of statistical performance.
Tools and methods: R · Monte Carlo simulation · CI/testing
PlanMCI
Study design under budget constraints
ANCOVA-based power and minimum detectable effect calculations for mild cognitive impairment trials.
My contribution: Developed the R package and interactive Shiny app to explore feasible designs and power under study budget constraints.
Tools and methods: R · Shiny · ANCOVA
LLM evaluation
Inference with noisy automated judgments
Statistical debiasing methods for LLM-as-a-judge evaluation.
My contribution: Conducted simulation studies comparing Rogan–Gladen and PPI/PPI++ estimators, assessing bias, interval coverage, and interval width.
Tools and methods: R · Monte Carlo simulation · Prediction-powered inference
