The Mother of all Meta-Analyses

So I’ve been preparing a new version of my introductory biostatistics course for the past 2 weeks, and I decided to incorporate most of the videos in the Annenberg Learner online course Against All Odds.  One of the videos I’m using is Correlation, which has an interesting discussion on twin studies, addressing the perennial “nature vs. nurture” question.  So what do I run across in my daily blog reading, but this Nature Genetics paper,  Meta-analysis of the heritability of human traits based on fifty years of twin studies.  Talk about luck.  One the lectures in a week following the one on correlation is an introduction to meta-analysis.  Double play!

Tip from James Thompson at Psychological comments,  who seems very pleased with the paper.
