The above article says “correlated variables shouldbe removed for PCA, as PCA places more importance on the correlated variables”. But whereas other article “https://www.analyticsvidhya.com/blog/2016/03/practical-guide-principal-component-analysis-python/” and many other articles say that PCA is used when we come across correlated varibles. So should I remove correlated varibles before PCA or don’t remove them?
