Modeling Clustered Heterogeneity: Fixed Effects, Random Effects and Mixtures
Although each statistical unit on which measurements are taken is unique typically there is not enough information available to account totally for its uniqueness. Therefore heterogeneity among units has to be limited by structural assumptions. One classical approach is to use random effects models, which assume that heterogeneity can be described by distributional assumptions. However, inferen...
متن کاملShould I Use Fixed or Random Effects?
Empirical analyses in political science very commonly confront data that are grouped— multiple votes by individual legislators, multiple years in individual states, multiple conflicts during individual years, and so forth. Modeling these data presents a series of potential challenges, of which accounting for differences across the groups is perhaps the most well-known. Two widely-used methods a...
متن کاملA model for integrating fixed-, random-, and mixed-effects meta-analyses into structural equation modeling.
Meta-analysis and structural equation modeling (SEM) are two important statistical methods in the behavioral, social, and medical sciences. They are generally treated as two unrelated topics in the literature. The present article proposes a model to integrate fixed-, random-, and mixed-effects meta-analyses into the SEM framework. By applying an appropriate transformation on the data, studies i...

ion of Analytic Methods in PropensityScore–Matched Samples The following information was abstracted from each of the published articles: (1) the method by which propensity-score– matched pairs were formed; (2) whether the authors assessed the balance in measured baseline characteristics between treated and untreated subjects in the matched sample, and when the authors did so, whether appropriat...
متن کاملFixed and Random Effects in
Received analyses based on stochastic frontier modeling with panel data have relied primarily on results from traditional linear fixed and random effects models. This paper examines extensions of these models that circumvent two important shortcomings of the existing fixed and random effects approaches. The conventional panel data stochastic frontier estimators both assume that technical or cos...
