Hypothesis testing, great style and double decent

Week 43-2023 [Issue 11]

Welcome to The Repo! 🚀

Great work deserves to be shared. Especially in data science.
Each week, I'll curate three gems from the data science community:

🗄️ Re: Remarkable Repository
💻 P:   Prolific Programmer
🏢 O:  Outstanding Organization

I hope you find them as valuable and insightful as I do.
You can find all recommendations in the GitHub repository at finnoh/repo!

tidymodels/infer

🗄️ Repository | “An R package for tidy statistical inference”

The infer package provides you with a framework for frequentist hypothesis testing. First you specify a hypothesis and then you compare the observed data with data that we would expect under this hypothesis.

I can see this not only as a helpful tool for your own project, but also as a great for explaining hypothesis testing to students in a more applied fashion.

Also, take a look at infer’s extensive documentation!

Michael Clark

💻 Programmer | Statistics, Data, Science

Michael Clark is a Senior Machine Learning Scientist at Strong Analytics, and has previously obtained a PhD in Psychology.

On his blog he writes about a wide range of topics, from Deep Learning for Tabular Data, to the concept of Double Decent, which refers to an overfitted model’s test error decreasing again when further increasing the model complexity.

Thank you for your work Michael!

The Tidyverse Style Guide

🏢 Organization | “Good coding style is like correct punctuation”

Good coding style is like correct punctuation: you can manage without it, butitsuremakesthingseasiertoread.—tidyverse style guide

On the internet you can find many, many, resources on how to write your code.

Many of them have great ideas, some of them offer a coherent philosophy on how to write any code in any language.

One such resource, albeit with a strong focus on R’s tidyverse framework, is the Tidyverse Style Guide.

I recommend taking a look and adapting some of the suggestions for your next R/Python/Julia/… project.
