Dr. Andridge's research is focused on imputation methods for missing data, primarily in large-scale probability samples. In particular, she works on methods for imputing survey data when missingness is driven by the missing values themselves (missing not at random). She also is involved in research on statistical issues in group-randomized trials. She collaborates with researchers across campus, including the Institute for Behavioral Medicine Research, the Nisonger Center for Excellence in Developmental Disabilities, and The OSU Comprehensive Cancer Center.
