I do data science for the City of Los Angeles. Prior to that, I worked at Impact Lab. The Center for Data Science and Public Policy. I spend a lot of time thinking about urbanism, data pipelines and tacos. Below are some selected projects of mine. I also write about food. That persona lives at Tacos and Coffe. An open software project designed around replacing some of the tooling for extracting and analyzing school data. More to come! Helped build, proto.

Who refuses to do arithmetic is doomed to talk nonsense. Covariate-Based Diagnostics for Randomized Experiments are Often Misleading. These people will be completely randomized in order to assign them to treatment or control. What is an Interaction Effect? By John Myles White.

Code used in this post was written for Julia v0. And, when applicable, reflects the state of packages used on 2018-03-23. You may need to modify it for different versions. When simulating models with random components, it is frequently advantageous to decompose the structure into. Is 150x faster, and this.

Is a high-level, high-performance dynamic programming language for numerical computing. It provides a sophisticated compiler, distributed parallel execution. Numerical accuracy, and an extensive mathematical function library. In addition, the Julia developer community is contributing a number of external packages. A collaboration between the Jupyter.
