Ken Bollen's research focuses on developing statistical methodology with applications across a range of population and health areas. His expertise on latent variable structural equation models provides a means to control for measurement error when testing hypotheses. For instance, a 2013 Statistics in Medicine article analyzes fetal conditions as a latent variable that mediates the effects of the mother's traits (e.g., smoking, age, parity) on birth weight, birth length, and gestational age. He also continues his work on advancing longitudinal methodology, causal indicators and measurement theory, new robust instrumental variable estimators for latent variable models, and proposing new approximations to Bayes Factors to help in model selection. In addition, Bollen is investigating diagnostic test procedures to determine whether weights are required when analyzing complex survey data.
As a statistical consultant for CPC, Bollen provides statistical advice for many CPC Fellows and students. He will continue his work with Adair examining the "fetal origins" hypothesis using the Cebu data study based at CPC. He is part of a similar fetal origins project for the United States as Subproject III on the new round of the Add Health NIH grant. As a CPC preceptor he also is working with a CPC trainee investigating the connections between graphical models and structural equation models.
