For example, diameter in site 1 (diam1) is a different variable from diameter in site 2 (diam 2).
We can also think of a trait measured in two sites as separate, but correlated, traits. We have 100 families, with 30 trees each, in sites A and B, for a total of 6,000 trees (100 x 30 x 2). We can get a better handle of the question if we use a simple example let’s assume that we have two traits (call them tree stem diameter and stem density) assessed in two sites (localities).īecause this is genetics we have a family structure, let’s say half-siblings so we only half the mother in common, and we will ignore any experimental design features to keep things simple. The email wasn’t a challenge but a simple question: Is it possible to run a multivariate analysis in multiple sites? I was going to answer yes, of course, and leave it there but it would be a cruel, non-satisfying answer.
