I’m currently teaching a computational linguistics course, and for just the second time, I’m using Github Classroom to manage assignments. I might make a few posts about what I’ve learned in the process, but for now, I think I’ll focus on what’s gone right, and what’s been more challenging in using Github Codespaces. Github Codespaces A Github Codespace is basically a virtual machine hosted by Github with VS Code as the default interface.

I’m still thinking about priors, distributions, and logistic regressions. The fact that a fairly broad normal distribution in logit space turns into a bimodal distribution in probability space has got me thinking about the standard deviation of random effects in logistic regression.

This summer, I’ve been spending some time getting more familiar with the nitty-gritty of Bayesian models, and I’m working on some modelling in Stan for logistic regression. Setting up the basic model formula in Stan for logistic regression is pretty straightforward: mu = intercept + slope * x; y ~ bernoulli_logit(mu); And then you “just” need to set a prior for for the intercept and slope terms.
