Multivariate analysis with R or Primer?

Interesting post from Marti Anderson explaining similarities and differences between adonis in R and the Primer + Permanova package (beyond cost 😊).

Her take-home message: R and Primer are both great, as long as you think about what you’re doing and understand what your R package is actually doing. We could hardly disagree with that!

Importantly, Marti describes important differences when fitting mixed models to multivariate data sets, with, at the moment, only Primer fitting mixed models appropriately.

We recommend several authors for keeping your perspectives broad, including Andrew Gelman and his colleagues. He and Aki Vehtari have just released a companion to their Regression and Other Stories, featuring classroom exercises, stories and demonstrations, practice questions, etc. Active Stories is self-described as “a perfect teaching aid, a perfect adjunct to a self-study program, and an enjoyable bedside read if you already know some statistics”, and Gelman describes it as lots of fun to write. We haven’t read it yet, but we will 😉
