Where or what is production? What does it mean when someone says to bring some data science product ‘in production’ ? What does it mean for data science products to be in production? Is your product already in production? Is it a magica...

This is the latest in my series of screencasts demonstrating how to use the tidymodels packages, from just getting started to tuning more complex models. Today’s screencast walks through how to use spatial resampling for evaluating a model, with this...

In the last post we explored how to build a particle swarm optimiser from scratch. In this post, let’s explore how we can leverage such an optimiser to perform mean variance optimisation to find optimal portfolios that satisfy certain constraints...

In the previous post we looked at creating market orders on Binance using the {binance} package. Today we’re going to dig into limit orders. Market Orders & Limit Orders What’s the difference between a market order and a limit order? I’m so glad you asked. In the BTC/...

The 30-Day Map Challenge is on again, and I’m hoping to be able to scrounge some time to get an entry for each day. Day 2 is lines (Day 1 was posted on Twitter only) and — while I’m hoping to focus on saving U.S. democracy for the majority of ...

Visualizing table data is no small task. It requires both data manipulation and data visualization skills from the technical end. It also requires knowledge about your audience. Ask yourself — For whom are you visualizing the data? Do you need interactivity? Will you include the table in a web application? The ...
