@erictleung cluster analysis is chapter 8 of that book i am reading, not there yet
cluster analysis is chapter 8 in this book, "multivariate data analysis" (Black and Hair)

anyone want to study multivariate statistics with me?

would be cool to get a study group going, its 15 chapters and lots of exercises

Hi people you can join me in my channel "mathematics"
Its 700 pages (index starts at 734).
I think If we do this book, we will be more then knowledgable about multivariate statistics

Not sure if we should use R or something else, I think we should stick to R))

@jacobbogers could you try some of those analyses on our data instead? Then we can all learn from your examples.

Ahh! @jacobbogers I found that you studied in Delft!!! Leuk!!! How did you find it? Applied Physics is a bit tough! Did you have to do that in Dutch?

@evaristoc I think you mentioned needing a hand with responsive D3.js. I still don't have experience with it but I was interested in responsive behavior for charts. If you haven't stumbled upon this StackOverflow post, it looks promising.

I've been studying support vector machines lately and ran into some really good material to understand it. This lecture at MIT (49 minutes) has a wonderful professor teaching this concept. I don't think there are many prerequisites to understand it. Some linear algebra may help.

The one thing I didn't quite understand that was brought up was Lagrange multipliers, but found this (10 minutes) to help me understand that. Cheers!

provision, of course, you need to Finnish first year analysis (is that called in USA?) and linear algebra, .., an introductions course in statistics (know how to derive student T distribution etc)

@erictleung thanks! really good.

@darwinrc I remember you were taking the Andrew Ng course in ML? He explains SVM in a very straight forward way. Want to get a better idea about the deduction of the SVM then check @erictleung's provided link above (the MIT Lecture by Winston): EX-CE-LLENT!!!

Furthermore: Are you into mathematical history, and want to know about a contemporary story? Just a simple anecdote about how long passed before people started taking seriously the work by V. Vapnik and Chervonenkis on SVM?? 30 years!!!. Check the last minutes of the MIT youtube lesson to know more...

Well, people like Copernicus had a worse time though... But that still says a lot about how lucky you must be anyway...
