Marios Michaelidis updated MATH-857:
------------------------------------
Attachment: Multicolinearity.java
This is the latest Multicolinearity class file with the copyright note removed.
Generally my background is more like in Risk and Statistics and therefore I
find myself in lack of the specific vocabulary (and generally the processes for
software deploymnent) that is being used here! I do apologise for that. I
googled this "SVM diff" and it gives me various links. Do you have a specific
link for that?. As for the style and formatting, I though eclipse was helping
me for that... if not what should I do to improve it in an easy way?
Regards

> Multicollinearity is a statistical phenomenon in which two or more predictor
> variables in any multiple regression model are highly correlated. Tolerance
> and VIF are checks that allows to avoid optimization failes due to "inability
> to converge". Most of the times, the major packages (SAS, SPSS etc), have a
> check prior to running the model and they exclude variables that might cause
> these kind of problems. It is quite a useful tool to be in common maths.
