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...
MOMENTS method (Statistics)The fixed effect meta-analytic structural equation modeling (MASEM) model assumes that the population effect is homogeneous across studies. It was first developed analytically using Generalized Least Squares (GLS) and computationally using Weighted Least Square (WLS) meth...

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 ...

The rank correlation test introduced by Begg and Mazumdar is extensively used in meta-analysis to test for publication bias in clinical and epidemiological studies. It is based on correlating the standardized treatment effect with the variance of the treatment effect using Kendall’s tau as the meas...
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...
