SUMMARY:Lecture / Discussion:MPSDS / JPSM Seminar Series:  Sensitivity Analyses for Nonignorable Selection Bias When Estimating Subgroup Parameters in Nonprobability Samples: A Weighting Approach
DESCRIPTION:MPSDS / JPSM Seminar Series\nMPSDS M3 Series: Mastery\, Methodology\, Meetups\n\nIn person\, room 1070 Institute for Social Research\, and via Zoom. \nThe Zoom call will be locked 10 minutes after the start of the presentation.\n\nSensitivity Analyses for Nonignorable Selection Bias When Estimating Subgroup Parameters in Nonprobability Samples: A Weighting Approach\n\nSelection bias in survey estimates is a major concern\, affecting both nonprobability samples and probability samples with low response rates. The proxy-pattern mixture model (PPMM) offers a method for conducting a sensitivity that assumes a nonignorable selection mechanism\, where selection depends on survey outcomes of interest. This approach requires summary-level auxiliary information for the target population of interest from a reference data source. While PPMM methods have been successfully applied to derive overall population-level estimates\, extension to domain-level estimates is challenging when population-level summaries for the specific subgroup are unavailable. This occurs when the domain indicator is observed only in the survey\, or for complex intersectional subgroups where stable/reliable population-level auxiliary variable estimates are unavailable. To combat this issue\, we propose a novel approach: creating nonignorable selection weights based on the PPMM based on a re-expression of the PPMM as a selection model. These weights can be directly applied to calculate domain-level estimates\, circumventing the need for domain-specific population-level summaries of auxiliary variables. They rely on a single sensitivity parameter (ranging from 0 to 1) that captures a spectrum of nonresponse assumptions\, ranging from an ignorable mechanism to an extreme nonignorable mechanism. We discuss differences in weight construction for continuous versus binary outcomes\, describe the necessary assumptions for these weights to produce informative domain-level estimates\, and illustrate properties through simulation. We then apply the approach to the Census Household Pulse Survey to estimate various subgroup quantities under a range of assumptions on the selection mechanism.\n\nRebecca R. Andridge\, PhD\nThe Ohio State University\nCollege of Public Health\, Division of Biostatistics\nAssociate Dean for Undergraduate Studies\nProfessor of Biostatistics\n\nDr. Andridge's research is focused on imputation methods for missing data\, primarily when missingness is driven by the missing values themselves (missing not at random)\, and on measures of selection bias for nonprobability samples. She also works on statistical challenges that arise in analysis of data from 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\, and serves as Lead Methodologist for several state-sponsored population-based surveys. She is an Elected Fellow of the American Statistical Association (2020).

SUMMARY:Workshop / Seminar:Power and Partnerships in Community Engagement
DESCRIPTION:Developing equitable and mutually beneficial partnerships with community members and organizations requires taking a critical look at how power operates in university-community partnerships. This interactive workshop will introduce participants to key principles of equity-focused community engagement and discuss how relationships of power shape university-community partnerships for research and student learning. We’ll consider how power operates in such areas as: the structure and terms of partnership agreements\, participation dynamics in university-community projects\, and funding/compensation. Participants will generate strategies for re-shaping inequitable power dynamics\, share insights with colleagues\, and identify ways to apply key principles to their own community-engaged work. \n\nThis session is designed especially for participants who are involved in (or interested in) community-engaged research\, teaching & learning\, project/program administration\, and/or campus initiatives at Michigan. \n\nOpen to faculty\, staff\, admin\, and post-docs. Graduate students who are interested in attending can email ginsberginfo@umich.edu for more information.\n\nThis session is not open to undergraduate students.\n\nRegister: https://sessions.studentlife.umich.edu/track/event/session/104215

SUMMARY:Exhibition:Revolutionary Paine: Andy Murphy Student-Curated Class Exhibit Common Sense
DESCRIPTION:Thomas Paine’s “Common Sense” was one of the most influential works of the American Revolution. The first edition was published on January 10\, 1776\, with an initial print run of just 1\,000 copies\; but within weeks demand soared. The students of Andy Murphy’s POLISCI 495 course co-curated the exhibition “Revolutionary Paine” to document the whirlwind caused by its publication. On view at the Clements January 16-May 8\, weekdays from 12-4 pm.
