On parameters estimation procedures in multilevel models
2003We examine maximum likelihood estimation procedures in multilevel models related to two-level hierarchically structured data. Usually, for fixed effects and variance components estimation, multivariate normal distribution is assumed. Here we consider for random effects multivariate exponential power distribution (MEP), which represents one of the ...

Multilevel Meta-Analysis: A Comparison with Traditional Meta-Analytical Procedures
Educational and Psychological Measurement, 2003In this article, the authors compare the multilevel meta-analysis approach with the more traditional meta-analytical approaches. After a description and comparison of the under-lying models and some of the major techniques, the results of the multilevel approach are compared with those of the traditional approaches, using a simulation study.

Engineering Optimization, 1996
Abstract A multidisciplinary design optimization procedure is developed for the simultaneous improvement of sonic boom, aerodynamic and structural performance of high speed aircraft. The coupled problem is decomposed into two levels of optimization. At the first level, optimization is performed for simultaneous reduction in sonic boom and improvements ...

Analyzing multilevel data with QCA: yet another straightforward procedure
Quality & Quantity, 2014A significant body of social-scientific literature has developed contextual theories. In a recent contribution to Quality & Quantity, Denk and Lehtinen (Qual Quant 48(6):3475–3487, 2014) present Comparative Multilevel Analysis (CMA) as an innovative method whereby the effects of contexts on outcomes of interest can be studied configurationally if ...
