Hi Jianying: I hope you are doing well and having a nice week so far. I hate to bother you with this question, but depending on whether I will have the data to do so, I may be running a principal component analysis on some past data from the lab. I need to speak with Dr. Kleeberger tomorrow morning so that I can clarify some things, but if possible, would you possibly be available to meet sometime tomorrow afternoon or anytime on Friday so that I can discuss the principal component analysis? I just want to be sure I do it correctly and I would feel better knowing I had your expertise. If you do not have the time, though, please do not worry and know that I understand . Thank you for your consideration, regardless. Sincerely, Heather
Well, I found a very good lecture note from PennState on Principal Component Analysis
