Nonlinear mediation in clustered data : a nonlinear multilevel mediation model [PDF]
, 2013 textMediational analysis quantifies proposed causal mechanisms through which treatments act on outcomes. In the presence of clustered data, conventional multiple regression mediational methods break down, requiring the use of hierarchical linear modeling

Use of posterior predictive assessments to evaluate model fit in multilevel logistic regression [PDF]
, 2009 Assessing the fit of a model is an important final step in any statistical analysis, but this is not straightforward when complex discrete response models are used.

Mean exit times and the multilevel Monte Carlo method [PDF]
, 2013 Numerical methods for stochastic differential equations are relatively inefficient when used to approximate mean exit times. In particular, although the basic Euler–Maruyama method has weak order equal to one for approximating the expected value of the ...

Performance of likelihood-based estimation methods for multilevel binary regression models. [PDF]
By means of a fractional factorial simulation experiment, we. compare the performance of penalised quasi-likelihood (PQL), non-adaptive Gaussian quadrature and adaptive Gaussian quadrature in estimating parameters for multilevel logistic regression ...

Comparison between flying capacitor and modular multilevel inverter [PDF]
, 2009 The paper describes the operational principle of flying capacitor and modular multilevel inverters. The detailed discussions of dc link capacitors voltage balancing methods for both inverters are given in order to enable fair comparison. The causes of dc

Zero-Inflated Generalized Linear Mixed Models: A Better Way to Understand Data Relationships
Mathematics, 2021 Our article explores an underused mathematical analytical methodology in the social sciences. In addition to describing the method and its advantages, we extend a previously reported application of mixed models in a well-known database about corruption ...

Homework and Academic Achievement in Latin America: A Multilevel Approach
Frontiers in Psychology, 2019 The relationship between homework and academic results has been widely researched. Most of that research has used English-speaking, European or Asian samples, and to date there have been no detailed studies into that relationship in Latin America and the

Fitting Multilevel Factor Models
SIAM Journal on Matrix Analysis and ApplicationsWe examine a special case of the multilevel factor model, with covariance given by multilevel low rank (MLR) matrix~\cite{parshakova2023factor}. We develop a novel, fast implementation of the expectation-maximization algorithm, tailored for multilevel factor models, to maximize the likelihood of the observed data.
