StatQuest: PCA in Python

You asked for it, you got it! Now I walk you through how to do PCA in Python, step-by-step. It's not too bad, and I'll show you how to generate test data, do the analysis, draw fancy graphs and interpret the results. If you want to download the code, here's the link to the StatQuest GitHub:

⭐ NOTE: When I code, I use Kite, a free AI-powered coding assistant that will help you code faster and smarter. The Kite plugin integrates with all the top editors and IDEs to give you smart completions and documentation while you’re typing. I love it! https://www.kite.com/get-kite/?utm_medium=referral&utm_source=youtube&utm_campaign=statquest&utm_content=description-only
