Do order of RDA axes correspond to explained variance of explanatory variables? #686

Closed aguilart closed 2 months ago

aguilart commented 2 months ago

Hello, I am doing an RDA where my matrix of response variables (morphological traits of individuals) is modeled against two explanatory variables and their interaction. Something like: traits ~ time * treatment. When I look at the variance explained by the factor I get the following order: time explains more, then treatment and last the interaction. As I get three RDA axes, am I right to assume that the first RDA axes correspond to time; the second to treatment and the third to the interaction?

Is this a fair way to interpret the axes?

Thanks!
