I have a set of observations of a variable Z (shown as the colormap) as a function of two other variables A and B. I want to study how Z varies with respect to A, B, and both A and B (eg. if A increases, does Z increase or decrease? Same with respect to B?)
The only problem is that my observations of Z are highly biased, i.e., for low A, B is high, and vice-versa.
Is there any way I can disentangle both dimensions (A and B)?
Right now, I have just studied Z for A < 1.75, as A doesn't vary too much in this window.
