StatQuest: PCA in Python смотреть онлайн

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:
