From Longhorn to Badger

It’s taken me a while to finally get around to updating my website with some personal news. I’ve moved from UT Austin to the UW Madison School of Education, where I am now an associate professor in the Educational Psychology Department’s Quantitative Methods program.

What do meta-analysts mean by 'multivariate' meta-analysis?

If you’ve ever had class with me or attended one of my presentations, you’ve probably heard me grouse about how statisticians are mostly awful about naming things.1 A lot of the terminology in our field is pretty bad and ineloquent.

Weighting in multivariate meta-analysis

One common question about multivariate/multi-level meta-analysis is how such models assign weight to individual effect size estimates. When a version of the question came up recently on the R-sig-meta-analysis listserv, Dr.

An update on code folding with blogdown + Academic theme

About a year ago I added a code-folding feature to my site, following an approach developed by Sébastien Rochette. I recently updated my site to work with the latest version of the Academic theme for Hugo, and it turns out that this broke my code-folding implementation.

Simulating correlated standardized mean differences for meta-analysis

As I’ve discussed in previous posts, meta-analyses in psychology, education, and other areas often include studies that contribute multiple, statistically dependent effect size estimates. I’m interested in methods for meta-analyzing and meta-regressing effect sizes from data structures like this, and studying this sort of thing often entails conducting Monte Carlo simulations.
