  • Demystifying Posterior Distributions

    Han Du, Fang Liu et al.•ARTICLE•Multivariate Behavioral Research•2026

    Bayesian statistics have gained significant traction across various fields over the past few decades. Bayesian statistics textbooks often provide both code and the analytical forms of parameters for simple models. However, they often omit the process of deriving posterior distributions or limit it to basic univariate examples focused on the mean and variance. Additionally, these resources frequently assume a strong background in linear algebra an…

  • To Disaggregate or Not to Disaggregate

    Open Access•Remus Mitchell, Craig K Enders et al.•ARTICLE•Multivariate Behavioral Research•2026

    It is routinely recommended that level-1 variables in multilevel models be disaggregated when they are of substantive importance. Yet, the consensus on the disaggregation of level-1 covariates is more mixed. Disaggregation clarifies interpretation and reduces bias in the covariate, though some methodologists argue that it is unnecessary when the covariate itself is not of substantive interest. Our study builds off recent work to explore the trade…

  • The Role of Prior Knowledge in Effects of Embodied Pedagogies on Learning

    Icy Zhang, Alice Xu et al.•ARTICLE•Journal of Educational Psychology•2025

    Background: Embodied learning pedagogies are increasingly popular, but our understanding of how embodied pedagogies enhance learning of complex concepts in higher education over longer periods of time remains nascent, particularly how learners’ prior knowledge might interact with different types of embodied pedagogies. We propose the Performing First Hypothesis as an organizing framework, which posits that learners with lower prior knowledge, bec…

  • An Investigation of Factored Regression Missing Data Methods for Multilevel Models with Cross-Level Interactions

    S Natasha Beretvas, Brian T Keller et al.•ARTICLE•Multivariate Behavioral Research•2023

    A growing body of literature has focused on missing data methods that factorize the joint distribution into a part representing the analysis model of interest and a part representing the distributions of the incomplete predictors. Relatively little is known about the utility of this method for multilevel models with interactive effects. This study presents a series of Monte Carlo computer simulations that investigates Bayesian and multiple imputa…

  • A Bayesian Latent Variable Selection Model for Nonignorable Missingness

    Han Du, Craig K Enders et al.•ARTICLE•Multivariate Behavioral Research•2022

    Missing data are exceedingly common across a variety of disciplines, such as educational, social, and behavioral science areas. Missing not at random (MNAR) mechanism where missingness is related to unobserved data is widespread in real data and has detrimental consequence. However, the existing MNAR-based methods have potential problems such as leaving the data incomplete and failing to accommodate incomplete covariates with interactions, non-li…

  • Is Item Imputation Always Better? An Investigation of Wave-Missing Data in Growth Models

    Juan Diego Vera, Craig K Enders•ARTICLE•Structural Equation Modeling: A…•2021

    Questionnaire data present challenges, as a missing item of a multi-item scale would lead to a total missing scale. A researcher applying multiple imputation to an incomplete multi-item questionnaire can impute the incomplete items prior to computing scale scores or impute the scale score entirely. Methodologist have favored item-level imputation because it greatly enhances precision in comparison to scale-level imputation; however, this benefit …

  • A Comparison of Multilevel Imputation Schemes for Random Coefficient Models

    Craig K Enders, Timothy Hayes et al.•ARTICLE•Multivariate Behavioral Research•2018

    Literature addressing missing data handling for random coefficient models is particularly scant, and the few studies to date have focused on the fully conditional specification framework and "reverse random coefficient" imputation. Although it has not received much attention in the literature, a joint modeling strategy that uses random within-cluster covariance matrices to preserve cluster-specific associations is a promising alternative for rand…

  • The Effects of Middle School Weight Climate on Youth With Higher Body Weight

    Open Access•Jaana Juvonen, Leah M Lessard et al.•ARTICLE•Journal of Research on Adolescence•2018•Referências: 8

    This study examines whether social-emotional difficulties associated with higher body weight vary across schools as a function of the school's weight climate. Weight climate, characterized by weight-policing, was assessed indirectly by examining how strongly self-reported weight predicts victim reputation within 26 ethnically diverse middle schools. Social-emotional indicators included self-reported loneliness, school belonging, and self-esteem. …

  • Centering Predictor Variables in Three-Level Contextual Models

    Ahnalee Brincks, Ahnalee M Brincks et al.•ARTICLE•Multivariate Behavioral Research•2017

    Hierarchical data are becoming increasingly complex, often involving more than two levels. Centering decisions in multilevel models are closely tied to substantive hypotheses and require researchers to be clear and cautious about their choices. This study investigated the implications of group mean centering (i.e., centering within context; CWC) and grand mean centering (CGM) of predictor variables in three-level contextual models. The goals were…

  • Evaluation of Multi-parameter Test Statistics for Multiple Imputation

    Yu Liu, Craig K Enders•ARTICLE•Multivariate Behavioral Research•2017

    In Ordinary Least Square regression, researchers often are interested in knowing whether a set of parameters is different from zero. With complete data, this could be achieved using the gain in prediction test, hierarchical multiple regression, or an omnibus F test. However, in substantive research scenarios, missing data often exist. In the context of multiple imputation, one of the current state-of-art missing data strategies, there are several…

  • Addressing Item-Level Missing Data

    Gina L Mazza, Craig K Enders et al.•ARTICLE•Multivariate Behavioral Research•2015

    Often when participants have missing scores on one or more of the items comprising a scale, researchers compute prorated scale scores by averaging the available items. Methodologists have cautioned that proration may make strict assumptions about the mean and covariance structures of the items comprising the scale (Schafer & Graham, 2002 Schafer, J.L., & Graham, J.W. (2002). Missing data: Our view of the state of the art. Psychological Methods, 7…
