How should we weight fishery data in stock assessments? Four students from the Punt lab recently attended the latest Center for the Advancement of Population Assessment Methodology (CAPAM) workshop on data weighting in stock assessments in sunny La Jolla, California. In total, eight students and post doctoral researchers from the University of Washington spent five days learning about data weighting, likelihoods, and diagnostics for model misspecification in stock assessments. Sessions were attended on site by over 100 fishery researchers from around the world and several online participants. UW students were featured in one workshop and two presentations. Additionally, past Punt Lab member Dr. James Thorson gave a keynote address titled: “What is the likelihood that your model is wrong? Generalized tests and corrections for overdispersion during model fitting and exploration.”
