Hello everyone...

I am really confused and I would like to ask some help from you.

I have a dependent variable named "D"
and two independent variables named "V" and "H"

The D variable can take the values 1 or 2 or 3 or 4 or 5

Same for V variable which takes the values V1, V2, V3

I have several triads of data as for example:

H1, V1, 1
H1, V2, 3
H1, V1, 2
H1, V2, 2
H3, V4, 5


I have attached an image as an example in order to explain better the problem.
