Bayesian SEM with BRMS

Note: for the most up to date version of this, see this post on rpubs Background So, it looks like brms version 2.0 implements multivariate responses – and hence piecewise Structural Equation Modeling in a Bayesian framework. After https://github.com/paul-buerkner/brms/issues/303, it became clear that while one cannot do tests of D-separation,...

Introducing the Open Derby (guest post)

Ensuring openness and reproducibility in ecology is an ongoing challenge, although open tools (e.g., R Studio, Github) are free to use, and user support is everywhere. To illustrate how ecology collaborations can fit within an open science framework, we had the idea of running an ‘Open Derby’. Similar to a research derby, where grad students and post-docs...

Which library to use to teach linear models & likelihood

I’ve been teaching likelihood to grad students for the past few years using the wonderful bbmle package from Ben Bolker. I really love it’s flexibility and the way you can get students into fitting anything their imagination can countenance. But there’s a small cost to that. First, their imagination, when they first meet likelihood, is….not ready. I...

Linear Model Power Analysis with Dplyr

I really liked the power analysis example I gave in class today. I feel like I’m finally firing on all cylinders with the tidyverse.

Let’s look at our seal fit again – maybe we want to...

You Complete Me

There’s a feature that is either new or I haven’t noticed before in the new release of tidyr that is making me giddy with giddiness. The complete function. This seems odd.

Other Writings about Parenting & Climate Change by Scientists

OK, so, I spoke too soon. There are at least a few stabs by scientists writing about being a parent who studies climate/environmental change. As folk send me more, I’ll try and keep this list updated. While there’s some great stuff here, I feel like this is an empty niche for some great writing. Maybe you want to contribute, too? Towards that end,...
