Given a sequence of observations yi with independent variances σi2, the inverse-variance weighted sum is given by Inverse-variance weighting is typically used in statistical meta-analysis(元分析) to combine the results from independent studies. http://en.wikipedia.org/wiki/Inverse-variance_weighting...

We performed fixed-effect meta-analysis based on inverse-variance weighting for HUNT, MGI, and ThyroidOmics in METAL61. Cochran’sQ-test62for heterogeneity has been conducted using METAL61. We performed genomic control correction prior to and after the meta-analysis. We identified LD-independent ge...

The outcome model used in the IPTW analysis was a linear regression of the outcome on treatment, weighted by the estimated propensity score. The variance of the IPTW treatment estimate was computed using the IPTW-W variance estimator that incorporates the uncertainty in the estimated propensity ...
Theivw_radial()function fits a radial inverse variance weighted (IVW) model using either first order, second order, or modified second order weights. It provides an effect estimate and allows for outliers to be identified using Cochran's Q-statistic. This function now also includes iterative an...
