For the past seven years, I’ve been working on multiple imputation and Bayesian estimation approaches to missing data, with an emphasis on multilevel data structures. With support from Institute of Educational Sciences awards R305D150056 (Craig Enders, PI; Roy Levy, Co-PI) and R305D190002 (Craig Enders, PI; Brian Keller and Han Du, Co-PIs), our research team has developed the standalone software package, Blimp. Blimp was originally designed as a multiple imputation program, but the application now offers general-purpose Bayesian estimation for a wide range of single-level and multilevel regression models with two or three levels, with or without missing data. In particular, the application offers estimation routines for interactive and polynomial effects that are not yet available in other software packages, including support for binary, ordinal, multicategoricual nominal, skewed continuous variables, and count variables. The third iteration of the software extends Blimp’s capabilities to accommodate multiple equations, including structural equation and latent variable models. Blimp is freely available for macOS, Windows, and Linux at www.appliedmissingdata.com/blimp.Curriculum Vitae
