Regression Test for Funnel Plot Asymmetry Model: mixed-effects meta-regression model Predictor: standard error Test for Funnel Plot Asymmetry: z = -0.4623, p = 0.6439 radial 星状图 主要反映各研究的异质性,从而发现异质性的点。弧线对应的效应评估大小分布。如下: ### radial plots res <- rma(yi,...
META REGRESSION在 Statistics Base Edition 中可用。 该命令必须后跟表示因果关系大小变量的单个数字变量。 (可选)BY(后跟要视为因子的变量名称) 可以跟在命令后面。 (可选)WITH可以后跟要视为协变量的数字变量名称。 语法表示元回归过程。 META REGRESSIONvariable[ BYfactor_list] [ WITHcovariate_list] [ /CRITE...

Regression analysis of deterministic and stochastic simulation models is introduced. Curve fitting, least squares method, high order approximation, and transformations are explained. Applications to optimization and control, and sensitivity analysis are outlined....
2. Cox比例风险回归模型(Cox proportional hazards regression models):纳人Meta分析的随机对照或队列研究中,常用Cox比例风险回归模型来计算HR,一般会直接给出校正后的HR值及其95%可信区间 3. Kaplan-Meier曲线:K-M曲线法是一种用于评估风险函数的非参数方法,不需要对生存时间的分布进行特殊指定,并图示化结果显示数据...
To identify the potentially relevant moderators in predicting the yield benefit of legume-based cropping system, a meta-regression model was fitted with 21 modifiers (Supplementary Table3) as predictors using the R packagemetaforest65. The approach is adapted from the machine-learning algorithm “rand...
Heterogeneity indicators for meta-regression models also included R2 as an additional metric for variance explained by the model.

Meta-regression allows for reactive optimization, in which system components self-organize to changing conditions in a manner that is robust, or affected minimally by other sources of variability. Meta-regression extends profiling, providing a methodology for model-building when there is incomplete ...
在 Meta分析时，需分析各研究间的异质性，并对 异质性的来源进行探讨 ，Meta回归 (meta—regression)分析可评价研究间异质性的大小及来源。一般认为，Meta回归分析是亚组分析的一种扩大，主要通过对多因素的效应量进行联合分析实现，仅当Meta分析纳入的研究数量在10个以上时才行此分析”。在 Meta回归里，将效应估计...
