Variance partitioning in multilevel models for count data

  title={Variance partitioning in multilevel models for count data},
  author={George Leckie and William J. Browne and Harvey Goldstein and Juan Merlo and Peter C. Austin},
  journal={arXiv: Methodology},
A first step when fitting multilevel models to continuous responses is to explore the degree of clustering in the data. Researchers fit variance-component models and then report the proportion of variation in the response that is due to systematic differences between clusters. Equally they report the response correlation between units within a cluster. These statistics are popularly referred to as variance partition coefficients (VPCs) and intraclass correlation coefficients (ICCs). When…

Reporting Practice in Multilevel Modeling: A Revisit After 10 Years
The results showed improvement in some areas of the reporting practices, but poor practices persist in terms of model specification, description of a missing mechanism, power analysis, assumption checking, model comparisons, and effect sizes.
Interviewers’ and Respondents’ Joint Production of Response Quality in Openended Questions. A Multilevel Negativebinomial Regression Approach
Open-ended questions are an important methodological tool for social science researchers, but they suffer from large variations in response quality. In this contribution, we discuss the state of
School value-added models for multivariate academic and non-academic outcomes: A more rounded approach to using student data to inform school accountability
Education systems around the world increasingly rely on school value-added models to hold schools to account. These models typically focus on a limited number of academic outcomes, failing to
School value-added models for multivariate academic and non-academic outcomes: exploring implications for performance monitoring and accountability
ABSTRACT Education systems around the world increasingly rely on school value-added models to monitor school performance and hold schools to account. These models typically focus on a limited number
Accounting for human-related unobserved heterogeneity in the safety performance of connected vehicles: An incorporation of Bayesian hierarchical negative binomial into simulated work zone warning application
Although this study was restricted to the CV-WZW application, the introduced delivery distance for CV notifications should be regarded in future studies as a contributing factor to the safety assessment of other CV applications.

Abstract The detection and interpretation of variability in archaeological data has been a long-standing effort in the field. This paper aims to introduce the application of Bayesian multilevel
The impact of city block type on residential burglary: Mexico City as case study
Using block level data for Mexico City as case study, this article provides evidence that the type of city block type correlates with the likelihood of residential burglary. We employed five
Who Supported the Early Muslim Brotherhood?
Scholarship on political Islam suggests that support for early Islamist movements came from literate merchants, government officials, and professionals who lacked political representation. We test


Variance partitioning in multilevel logistic models that exhibit overdispersion
A common application of multilevel models is to apportion the variance in the response according to the different levels of the data. Whereas partitioning variances is straightforward in models with
Partitioning variation in multilevel models
In multilevel modeling the residual variation in a response variable is split into component parts that are attributed to various levels. In applied work, much use is made of the percentage of
Measures of clustering and heterogeneity in multilevel Poisson regression analyses of rates/count data
The median rate ratio is the median relative change in the rate of the occurrence of the event when comparing identical subjects from 2 randomly selected different clusters that are ordered by rate and the variance partition coefficient is described, which denotes the proportion of the variation in the outcome that is attributable to between‐cluster differences that can be computed with count outcomes.
The Estimation of School Effects
The increasing public demand to hold schools accountable for their effects on student outcomes lends urgency to the task of clarifying statistical issues pertaining to studies of school effects. This

A Multilevel Modelling Approach to Measuring Changing Patterns of Ethnic Composition and Segregation among London Secondary Schools, 2001-2010
This work proposes multilevel random-coefficient multinomial logistic regression for the general case of statistically modelling multiple groups of individuals over multiple occasions and multiple organizational scales and illustrates this combined approach with an application to modelling changing three-group white–black–Asian ethnic composition and segregation among London secondary schools and local authorities during the first decade of the 21st century.

A general latent normal model for multilevel data with mixtures of response types is extended in the case of ordered responses to deal with variates having a large number of categories and including
Multilevel Modeling of Social Segregation
The traditional approach to measuring segregation is based upon descriptive, non-model-based indices. A recently proposed alternative is multilevel modeling. The authors further develop the argument
