meta‐analysisrandom‐effect modelrare eventsMeta‐analysis allows for the aggregation of results from multiple studies to improve statistical inference for the parameter of interest. In recent years, random‐effect meta‐analysis has been employed to synthesize estimates of incidence rates of adverse ...
总体来说,Panel model大多采用FE模型(异质性[非随机]截距)。 Meta-analysis里面的FE和RE分别对应于HLM的“固定斜率”和“随机斜率”,不过这里的“斜率”应理解为元分析不同Study的效应量。效应量本身可以看做是Level 1的斜率,而效应量的标准误则对应于Level 1(组内)的残差。总体来说,Meta-analysis大多采用RE模型...
“s”)ere because in a fixed effect model ,we assume that theffect sizes in our meta-analysis differ only because ofampl ing error and they al l share a common mean Our effect sizes differ from each other because each studysed a different sample of participants–and that is the only...

(redirected fromRandom effect model) random effects model A statistical model that may be used in meta-analysis, in which both within-study sampling error (variance) and between-studies variation are included in assessing the uncertainty or confidence interval of the results of the meta-analysis. ...
Over a few decades ago, meta-analysis has rapidly developed in various fields of studies to improve the quality of previous research by quantitative review. Quantitative review assesses an overall magnitude of the effect from multiple studies. Hence, the objective in this dissertation is to determine...
subgroup effects under the specified model, as described for example in chapter 19 of Borenstein et al "Introduction to Meta-analysis" (Wiley, 2009). Note that under the inverse-variance common-effect model, this approach is equivalent to variance partitioning as used in previous versions ofmetan...
We derive explicit formulas for R_r~2 in three special cases: the random intercept model, growth curve model, and meta-analysis model. Theoretical results are illustrated with three mixed model examples: (1) travel time to the nearest cancer center for women with breast cancer in the U.S....

There are two popular statistical models for meta-analysis, the fixed-effect model and the random-effects model. The fact that these two models employ similar sets of formulas to compute statistics, and sometimes yield similar estimates for the various parameters, may lead people to believe that ...
