Missing data are a ubiquitous feature of nearly all research applications, arising through participant non-response, attrition, and sometimes even by design. Failure to account appropriately for missing values when conducting statistical analyses can result in badly biased estimates and incorrect inferences about the relationships under study. Modern Missing Data Analysis is a three-day workshop focused on three optimal approaches for addressing missing data that can be applied across a variety of research settings: maximum likelihood, Bayesian estimation, and multiple imputation. Participants will learn details about the classic versions of these methods as well as state-of-the-art extensions that have been developed in the last five years. These procedures are advantageous because they use all available data and make realistic assumptions about the cause of missingness; estimates and significance tests are therefore valid in a broader range of situations than historical methods such as deleting incomplete data records. The purpose of this course is to provide participants with foundational knowledge about maximum likelihood, Bayesian estimation, and multiple imputation. Equally important, participants will learn how to select an appropriate missing data handling method and apply it to complex, real-world data sets. To this end, presentations will include a mix of theoretical information, practical tips, and computer applications.

Goals of the Workshop

Our motivating goal is to provide an interactive and engaging instructional experience that provides attendees with foundational knowledge about state-of-the-art missing data methods. Instructional time features an equal balance of core statistical concepts and practical data analysis applications. Statistical concepts are presented at a level that is fully accessible to researchers with a background in multiple regression. The workshop is designed to provide participants with the materials and instruction needed to understand core concepts; choose an appropriate missing data handling procedure; apply that procedure to complex, real-world data sets; and describe the methodology and results. Attendees should leave the course with a toolkit that fully prepares them to utilize cutting-edge missing data methods in their own work.

Who Should Attend

The workshop is designed for graduate students, post-doctoral fellows, faculty, and research scientists from the behavioral, social, and health sciences. Attendees should have a working knowledge of multiple regression, as statistical aspects of the workshop borrow heavily from these models. Participants who would like a refresher on linear regression prior to attending may wish to watch our (no cost) Linear Regression Playlist on YouTube.

Software Considerations

Pre-recorded software demonstrations are provided for self-paced learning. Maximum likelihood estimation is conducted using Mplus as well as the lavaan and mdmb packages in R. Note that R can be downloaded for free and all Mplus examples will run in the free demo version of the software, available at www.statmodel.com. Bayesian estimation and multiple imputation are conducted in Blimp. Blimp can be downloaded for free at www.appliedmissingdata.com/blimp. While it is helpful to have some familiarity with one or more of these programs, prior experience is not necessary. The accompanying software demonstration notes provide detailed instructions in how to use the different packages and data files and script are provided for all worked examples. The lectures that constitute the majority of the workshop are largely software-independent.

What is Provided

Modern Missing Data Analysis is a three-day workshop originally taught live via Zoom by Craig Enders. Daily lectures were held from 10:00 to 3:30 with morning, lunch, and afternoon breaks. Sessions consisted of comprehensive lectures, detailed presentation of real-data examples, response to participant questions, and general discussion. Pre-recorded software demonstration videos are also available in R, Mplus, and Blimp.

Self-paced participants will receive 12-month access to unlimited viewing of all original lecture recordings and software demonstrations as well as indefinite retention of extensive PDFs of lecture and computer demonstration notes and all associated computer scripts and data files.

Reviews

In an effort to continually improve our instruction we obtain student evaluations with each course offering. Here is a sample of reviews from prior workshops offered by Dr. Enders:

Craig is easily one of the best statistics professors I have ever had. He has taken an incredibly complex topic that I have previously struggled to understand and apply to my own data and made it possible for me to feel confident in using and interpreting the analyses on my own

Dr. Enders did a great job of explaining concepts in multiple ways when prompted to do so by student questions, and creating an atmosphere where students felt comfortable asking questions -- Dr. Enders welcomed both basic questions and those that were beyond the scope of the course but related to a student's own research interests.

I felt the slides were quite easy to understand and appreciated that there were figures which helped to illustrate conceptual understanding underlying each concept.

I benefited so much from this class, both in learning the material, and in the professor's example for effective pedagogy.

Prof Enders is a great lecturer. He puts complicated stats concepts in terms that are easy to understand, knows when to pause to let students process, and knows when to go over something multiple times/in multiple ways to maximize student understanding.

I really appreciated this class because it taught me practical skills of how to do statistics in my own research, but also helped me to concretely understand important concepts.
