Multivariate statistics and Machine learning - a full course - PCA : standardization and how to extract components

See all my videos at https://www.tilestats.com/ In this third video about PCA, we will learn when and why we need to standardize our variables before running a PCA. We will standardize variables based on a simple example. At min 11:05, we will also see how we can use the Kaiser criterion and the scree plot to extract components (reduce the dimensions).
