From papers to Julia code: examples wanted

General Usage

Ian Weaver Started a very nice discussion in Slack that could use some more community input:

We want examples were Julia code matches the paper pseudo code or mathematical specification.

Here are some examples people fished from twitter, but we’d love to see yours!

I made some performance concessions to keep it close to the paper’s equations, like computing the inverse of A.

Here is the package version (unregistered): GitHub - ew-git/PoissonFE.jl: Implements Poisson fixed effects regression and robust standard errors from Wooldridge (1999) in Julia. The implementation should be faster than GLM.jl with many fixed effects.

Thanks @miguelraz for the BeautifulAlgorithms.jl shout-out!

I have a few LaTeX Overleaf projects that compare algorithmic pseudocode you’d find in an academic paper with their Julia implementation counterparts:
