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(即HLM的随机斜率模型)。 参考文献 Borenstein, M., Hedges,...
fixed effect meta-analysis假定所有研究都估计固定的treatment effect,然而random effects meta-analysis允许不同研究中的treatment effect 差异。 fixed effect和random effects meta-analyses的区别:如下图,95%置信区间的Forest plots,fixed effect meta-analysis提供了对common treatment effect的最好估计,fixed effect假定...

In the meta-analysis setting, the adverse consequences of a false negative test are more profound than the disadvantages of a false positive test. Our alternative test improves the error rates in fixed effects meta-analysis. Its significance level equals the nominal value, and the Type II error...

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 ...
