Comparison of Two Meta-Analysis Methods: Inverse-Variance-Weighted Average and Weighted Sum of Z-Scores 来自 NCBI 喜欢 0 阅读量: 62 作者:CH Lee,S Cook,SL Ji,B Han 摘要: Meta-analysis of genome-wide association studies (GWAS) has achieved great success in detecting loci underlying human ...
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...

However, these methods may provide a substantially biased estimate of the inverse variance that is needed for the meta-analysis.Research Design: We use Basu's theorem to derive unbiased estimators for σ~?2 from the most commonly used sample summaries from the normal distribution. While there ...

Twin and family studies have indicated that ~ 40–70% of the inter-individual variance in BMI can be explained by genetic factors.11 Further, it is true that the increase in the prevalence of overweight and obesity worldwide can be attributed to changes in environmental factors, but the ...
We calculate the spatial distribution of diffracted power and its variance, then tune the duty cycle of each groove to minimize the variance across the meta scatterers rows (Fig. 2d). Every update in the iterative algorithm is performed as $$C_{i} = C_{i} - \delta \frac{{P_{i} -...
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...
