A meta-analysis example: “Quantifying the Influence of Climate on Human Conflict” Part II

My discussion of the meta-analysis continues in this video. Here, we’ll dive deeper into our methods, focusing on how we weighted different effects based on their precision and how we quantified heterogeneity across the studies. You’ll also learn more about the results of the analysis, as well as how we determined if there was any publication bias influencing the studies’ effects.

NOTE: This video includes some advanced material regarding the paper’s statistical analysis, so feel free to skip from 1:30 to 7:10 if you’re less comfortable with this kind of material or more interested in the bigger picture implications of the analysis.

Also NOTE: The chart at 7:09 may be too detailed to be read clearly on some devices. If this is the case for you, you can find a PDF version of the chart in the SEE ALSO section at the bottom of this page.
