An analysis of fertility differentials in Liberia and Ghana using multilevel models
… explanations of fertility, statistical models of fertility have rarely included an assessment of community effects.<br/><br/>The method of analysis used is multilevel modelling. This involves fitting variables measured at the woman level, variables measured at the community level and …

A Cross-national Study of Mathematics Achievement Via Three-level Multilevel Models
The present study explored the effects of the national and cultural contexts on students' mathematics achievement. The study also investigated the nature and magnitude of student-level (level 1), school-level (level 2), and country-level (level 3) factors that are associated with math achievement. …

Longitudinal multilevel models analyzing the trends of land use effects on non-driving travel choice
… a comparison approach with two cross-sectional multilevel Logit models using single-year data, a pooling approach by building one multilevel model with two-year data, and a longitudinal multilevel model. Empirical modeling results indicate that the longitudinal multilevel model is the most …

Methods for analysing complex panel data using multilevel models with an application to the Brazilian labour force survey
… of data complexity. These methods follow the Multilevel Model framework which is reviewed. Longitudinal growth curve models accounting for the complex data hierarchy are fitted. Recognizing the need to account for the complex correlation structure present in the data, multivariate multilevel …

Coastal Wetland Dynamics Under Sea-level Rise and Wetland Restoration in the Northern Gulf of Mexico using Bayesian Multilevel Models and a Web Tool
… such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological …

The Impact of Sample Size, Prevalence, Estimation Method and Other Factors When Estimating Multilevel Logistic Models
<p>Sample size guidelines for binary outcome multilevel models are rare, despite well-established rules-of-thumb for continuous outcome multilevel models. When considering requisite sample sizes for designing studies utilizing such models, applied practitioners would be remiss in failing to take …

Multilevel modelling of determinants of contraceptive method choice among women in South Africa
Multilevel models take into account various degrees of aggregation in the data. This study aims to bring together multilevel models from both frequentist and Bayesian perspectives in identifying determinants of contraceptive choices. The study uses the data from the 2016 South African Demographic …

A Moderator Model of Alcohol Use and Dating Aggression Among Young Adults
… 1 = 22.44), spanning six months. A series of multilevel models first examined how the links between alcohol use and dating aggression varied by the degree of both individual psychopathology as well as relationship risk. Main effects emerged such that alcohol use, individual psychopathology, …

Modelling malnutrition among under-five-year-old children in Ghana
… To answer the first and the second problems, multilevel models were considered. The results showed strong residual household-level variations in under-fives nutritional outcomes and that child’s age, type of birth, child’s experience of diarrhoeal episodes, size of child at birth and months of …

A Bayesian multilevel model for women unemployment in South Africa
… Bayesian estimation approach were applied to a multilevel logistic regression (MLR) model. Secondary data acquired from the Demographic and Health survey (DHS) held in South Africa in 2016 was used in the study. Information criteria revealed that the random intercept model outperformed the MLR …

Cognitive Processing Language in Communities of Inquiry: An Examination of Cognitive Presence, Instruction Modality, and Academic Performance of Online Learners
… analyses, we developed a series of regression models to examine relations between cognitive presence, instruction modality, academic performance, and cognitive processing language. We compared four multilevel models using phases of cognitive presence and instruction modality as predictors of …

Analysis of affective instability on ecological momentary assessments data: successive difference, variance decomposition, and mean comparison via multilevel modeling
… these measures be analyzed within generalized multilevel models. An illustrative example using EMA data on negative mood for borderline personality disorder (BPD) and major depressive disorder (MDD) groups is presented which shows that MSSD and PAC capture affective instability better than …

The Economy and Workplace Safety: Evidence from the Macro-Level
… observations), I estimated a series of nested multilevel models to explain the state-level variability in workplace safety as a function of local economic conditions. Results showed support for the hypothesized nonlinear, “U-Shape” curve between workplace safety outcomes and the state of the …

Leave No Crime Behind: Exposure to Violence and School Performance in New York City
… from New York City between 2006 and 2010, multilevel models were used to test whether exposure to violence in the school neighborhood (the number of police-reported felony assaults, homicides, rapes and robberies) predicts student performance (scaled scores on annual English and math …

Assertiveness during condom negotiation among high risk late adolescent/emerging adult couples: The role of relational uncertainty
… their romantic, opposite sex partner. Dyadic multilevel models revealed that hypotheses were not completely supported. While depressed men with high relational uncertainty showed low assertiveness, depressed women showed high assertiveness. Post-hoc analyses revealed a curvilinear relationship …

More Moments with Others Matter for Emotion Regulation and Well-Being: A Study of First-Year College Students’ Daily Life During COVID-19
… ER skills in a given moment? Results from multilevel models revealed that certain DBT ER skills (accumulating positives, building mastery, coping ahead) were consistently predictive of momentary well-being even when controlling for dispositional well-being. Moreover, on days of sufficient …

Mothers' personal distress and child dysregulation: joint contributions to change in maternal support in an emotionally challenging situation
… digital recordings of the snack delay. Tests of multilevel models revealed that mothers' personal distress was unrelated to maternal support ""in the moment"" (i.e., in intervals immediately following instances of within-child increase in dysregulation). However, mothers who reported higher …

Interactive contributions of children’s negative or positive behavior and maternal cardiac physiology to parenting in real time: An integration of biology and context
… Respiratory Sinus Arrhythmia (RSA). Results from multilevel models showed that when children displayed increases in negative emotions and behaviors in a given 15-sec interval of the task, mothers who displayed vagal augmentation (an index of social engagement) in the same interval displayed …
