The logic of Vector Linear Regression

Hi,
I have searched about vector linear regression on the web about the mathematical logic of the algorithm but didn't find anything.
It would help a lot if anybody helps me out with the mathematical aspect of vector linear regression and its difference with linear regression.
Thanks.

Hi,
as far as i know: Vector linear regression is a simple linear regression but with many labels. these are specified by having label_1 etc as role.

Hi,
did you deactivate everything fance e.g. removal of collinear features in the LinReg?

Hallo,
Please, have a look at these two videos produced by Ingo, one of the most senior persons from Rapidminer:

With a quick search along "Vector Linear Regression" & "Linear Regression", it is easy to find more formal (mathematical) explanation (algebra, vector theory).
Bonne chance,

FYI @IngoRM is one of two founders of RapidMiner (the other is @RalfKlinkenberg) and they literally wrote the first versions of RapidMiner back 10 years ago (it was originally called YALE). So yeah, @IngoRM is definitely one of our more senior members!

@sgenzer the operative word is "senior!" hehehe!
Thank you for the response.
But as you know support vector machines (and SVR) are something different than vector linear regression.
So, any difference between vector linear regression and support vector regression?
Thank you,
I implemented both linear regression and vector linear regression on a single labeled dataset, but the results were totally different!
So, any other idea about the differences of these two algorithms?
Thank you, it worked!
I unchecked the 'eliminate colinear features' and changed the feature selection to 'Iterative TTest'. Now the linear regression and vector linear regression are giving same results.
