Overview of matrices calculation (Part 1) / Übersicht zur Matrizen Rechnung (Teil 1)
Since in the multivariate statistics a lot of things can be displayed in matrix notation shorter, here is the first part of a short list of the most important formulas I will use in the further posts.
Da in der Multivariaten Statistik vieles in Matrix Schreibweise kürzer dargestellt werden kann ist hier der erste Teil einer kurzen Aufstellung der wichtigsten Formeln die ich in den weiteren Posts benutzen werde.

Nice post, Mathematicians rule the world!!!
Nice post !
Thanks alot , you just taught me what I really wanted
amazing, I am very impressed with people who are good at math, let alone matri..success is always ok.
Thanks very much but I am very week in math. How can I solve this problem.
As in most other things, exercise, exercise and exercise again. If you don't understand a formula, it is mostly because you didn't understand something before, then it makes more sense to go back one step instead of spending too much time with the formula.
Lol.to me its like you just performed a magic trick.....maths is really hard....sad face
