"Additive models are used when there is a similar magnitude amongst the models" and "Multiplicative [is] used when there is a large number of data or a lower magnitude between models". How do you know when the magnitude is similar or lower? Can the magnitude be higher? What, if anything, do these two types have to do with the four separation components?
