StatQuest: PCA - Practical Tips

This is a follow-up video for StatQuest: Principal Component Analysis (PCA), Step-by-Step https://youtu.be/FgakZw6K1QQ

In it, I give practical advice about the need to scale your data, the need to center your data, and how many principal components you should expect to get.

If you are interested in doing PCA in R see: https://youtu.be/0Jp4gsfOLMs

⭐ NOTE: When I code, I use Kite, a free AI-powered coding assistant that will help you code faster and smarter.
