This website is excellent, it’s extremely useful. It boasts very good techniques, elegant code, and is well-written and organised. It’s one of the best of its kind.
This site is really incredible. They understand the tools relevant to modern advanced scientific analysis--but teach it at the level of someone trying to build these skills from scratch. Incredible attention to detail.
Thanks Mr Kassambara for the great work and energy to share knowledge!! Really love your work!! Keep on going!!
Thank you so much for sharing your experience and information about this topic in such a nice way.
I like this PCA by the Kassambara but only one I hope is oriented around health e.g. PCA for heart failure readmission rate prediction. If something like this already there, please direct me.
