Was asked about collinearity again, so here's Vahove's 2019 post on why it isn't a problem that needs a solution. Design the model(s) to answer a formal question and free your mind janhove.github.io/posts/2019-0...

tl;dr

Collinearity is a form of lack of information that is appropriately reflected in the output of your statistical model.
When collinearity is associated with interpretational difficulties, these difficulties aren’t caused by the collinearity itself. Rather, they reveal that the model was poorly specified (in that it answers a question different to the one of interest), that the analyst overly focuses on significance rather than estimates and the uncertainty about them or that the analyst took a mental shortcut in interpreting the model that could’ve also led them astray in the absence of collinearity.
If you do decide to “deal with” collinearity, make sure you can still answer the question of interest.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Biodiversity doesn’t respond instantly to its driver, yet most assessments assume it does. 🚨

The paradigm shift we propose in considers multiple trajectories of long-term environmental changes and disturbance events that cumulate and push biodiversity into a quasi-permanent non-equilibrium state.

If you interested in modeling species ranges or biodiversity patters in space & time, our paradigm shift should be of interest to you 😉

Print version of graphic. Trees absorb carbon dioxide from the air and turn it into sugars, using the food to grow. This process, called photosynthesis, allows plants to make their own food, storing the carbon in their tissues as they grow roots, branches and leaves. In this way, trees help fight climate change by absorbing and storing carbon pollution that is heating the planet. Big trees store the most carbon because of their mass, and long-lived species such as Douglas fir and red cedar can lock carbon away for centuries. Trees absorb carbon dioxide gas through openings in leaves or needles called stomata. Chloroplasts within leaves and needles use the energy of the sun to split water molecules drawn up through tree roots into hydrogen and oxygen, released through their stomata. Trees and other green plants create the air we breathe, and shelter and nourish life as we know it.

We should broaden models, not narrow them. Models are tools to explore uncertainty, communicate scenarios, and test policy. Managers seek robust strategies, not perfect forecasts.
