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, available Wednesday on Soundcloud and iTunes.
