Steve MacEachern: Odds Were Always Good He’d Work in Statistics

Steve MacEachern, distinguished professor of statistics, discusses his field, how he got into statistics, and what feature he has to have in his job.

MacEachern earned a doctorate at the University of Minnesota, researching Bayesian methods, a way to use probability to represent uncertainty via prior and posterior distributions informed by data.

He sees statistics as different from data science/analytics because statistics emphasizes modeling and inference, while data science adds large-scale data capture and wrangling, often from computer science.

MacEachern discusses modern statistics’ growing focus on prediction in platforms like search and e-commerce, contrasts hard-science versus human-centered data, and outlines current research challenges driven by AI and massive predictor sets.

Laura Kubatko: It’s An Exciting Time to Be Working in Biology

Professor Laura Kubatko, from the Department of Statistics and the Department of Evolution, Ecology and Organismal Biology, is amazed by the advances she’s seen in her career in how scientists translate “observations into formal mathematical or statistical models.” Moreover, this is, for her, the “fun part,” because they collaborate to explain “why [we] think [an event] is happening.”

Statistical Modeling Can Coax More Information Out of Medical Studies, Says Elly Kaizar

Statistical modeling can reveal many hidden facts, such as the best time to start certain treatments for childhood traumatic brain injuries. Elly Kaizar, Professor of Statistics, has shown that statistically combining data from several sources gives us the opportunity to learn more about treatment effectiveness as it varies with different treatment implementations and across populations. Prof. Kaizar discusses this topic and more ways statistical analyses can mitigate imperfect data collection with host David Staley on this week’s Voices of Excellence.
