Vector Linear Regression - Multi Label
I'm trying to built a vector linear regression model with multiple label attributes, but I'm finding difficulties with the special role setup.
I read the vector linear regression description and from the below I understand that all labels must be named in its special role as something like "label_1", "label_2" and so on.
****The attributes forming the vector should be marked as special, the special role names of all label attributes should start with 'label'.*****
I'm sure that this must be easy, but whatever I've tried doesn't work.
Enclosed the example process and the data
Can you please shed some light on this?
