Hi, guys
I just failed to prove the way to derive the overall variance formula for fixed-effect model of a meta-analysis. By partial derivation the Log(likelihood function) of a fixed-effect model, it is easy to derive the formula for estimating the overall mean. However, I don't understand how the formula for estimating the overall variance comes from. Your help would be much appreciated. Thanks.

What is ANOVA?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
