[This was originally posted on my blog] I work a lot with what is sometimes termed ‘hierarchical’ data. That is, data that is clustered in some way. For me, those clusters are sometimes multiple observations from the same person — as is the case with longitudinal data or within-subject manipulations…

Using the new Turbo palette from Google in R

Note: This was originally posted on my blog. A couple days ago an AI engineer from Google posted about a new palette he developed. This palette, ‘Turbo’, is as colorful as the widely used ‘jet’ palette, but perceptually uniform and color-blind friendly like the viridis palettes. He shared code in…

Improving Genetic Prediction: Data cleaning & Meta-analysis

Improving the last prediction In my first post I showed how to build a simple model, using only genetic information, that predicts height with 53% accuracy in an independent sample. In this post I’m going to improve that model, which will ultimately result in a model with 64% accuracy in an independent sample —…
