StatShare Community of Practice

About StatShare

Welcome to the StatShare web page!

StatShare is a community of practice for non-faculty biostatisticians to share knowledge, learn, network, and support one another in solving difficult research problems they encounter in their work.

Dr. Kathleen Wannemuehler and Dr. Bret Hanlon, both Scientists in Biostatististics and Medical Informatics, lead StatShare.

If you have ideas for StatShare meetings, please reach out to Dr. Wannemuehler at or Dr. Hanlon at

How Does it Work?

When do we meet?

The StatShare community meets on the second Tuesday of the month during the academic year from 10:30-11:30 am.

Who Attends?

Non-faculty biostatisticians who are engaged in biomedical research are welcome to attend.

Title: Computational Tools for Implementing Best Practices in Propensity Score Analysis

Abstract: Propensity score analysis, including matching and weighting, is a popular method to adjust for confounding by measured confounding variables in observational studies. Rather than (or in addition to) including confounding variables in a regression of the outcome on the treatment, propensity score methods involve manipulating the sample to mimic the qualities of a randomized trial. In this talk, I will introduce propensity score analysis and describe a suite of R packages that can be used to implement best practices in their application. These packages include MatchIt, WeightIt, cobalt, and several auxiliary packages for more specialized cases and for implementing emerging methods.

Title: R Markdown for ‘old R Sweave dogs’
Abstract: Learn about R Markdown, its interactive features within RStudio, and supporting packages (knitr, kableExtra, plotly) to use for creating reports (pdf, html). With RStudio rebranding into Posit and recently launching Quarto, we’ll discuss its potential impact on the future of R.

Title: Optimal Allocation of Water and Sanitation Facilities To Prevent Communicable Diarrheal Diseases in Senegal Under Partial Interference

Abstract: For several decades, Senegal has faced inadequate water, sanitation, and hygiene (WASH) facilities in households, contributing to persistent, high levels of communicable diarrheal diseases. Unfortunately, the ideal WASH policy where every household in Senegal installs WASH facilities is impossible due to logistical and budgetary concerns. This work proposes to estimate an optimal allocation rule of WASH facilities in Senegal by combining recent advances in personalized medicine and partial interference in causal inference. Our allocation rule helps public health officials in Senegal decide what fraction of total households in a region should get WASH facilities based on block-level and household-level characteristics. We characterize the excess risk of the allocation rule and show that our rule outperforms other allocation policies in Senegal.

This is joint work with Chan Park (University of Pennsylvania), Guanhua Chen (UW-Madison), and Menggang Yu (UW-Madison).
