Congratulations to my student, Maggie Ma, for publishing her first #rstats package {ggincerta} on CRAN 🥳
Spatial uncertainty visualisation (bivariate, pixel, exceedance, glyph), like {Vizumap}, but fully integrated with ggplot2 -- a much simpler API with all the advantages of the ggplot2 system.

Oh look @bobohara.bsky.social a statistical analysis of species richness. If only someone had written an article about the issues with doing that...
In our new article led by Gabriele Midolo, published in Ecology Letters, we show that plant species richness in European plant communities generally decreased between the 1960s and 1980s. However, since the 1990s, this trend seems to have stopped or even reversed.

Last time at our cabin in Oppdal for a while, before the big move to Bayreuth. Hopefully we will be back next winter at least, then with snow 😀

Still plugging away at this. I've now expanded this idea of a kronecker covariance over the whole random effect for all structures in the glmmVA interface, i.e., also for corExp, corMatern, corAR1 and corCS, so that you can do things like corCS(a+b|group).
I'm sure this is useful for some reason.
I'm sure this is useful for some reason.
Many bugfixes and updates later... This will probably happen a few times. I've also added a propto() structure, which can be combined with a correlation matrix for random effects, forming a kronecker covariance structure where the column matrix is fixed.

An excellent course! Thanks so much for organising and running it, Bert & the whole team! Keeping my fingers crossed that there will be another one like it in the not too distant future, I can warmly recommend it!
Two weeks ago I organised the first Summer school in Model-based Multivariate analysis for community ecologists.
We spent a week in Hjerkinn (NO), teaching 26 international participants about model-based multivariate analysis. Together with Jenni Niku, Pekka Korhonen, Francis Hui and Audun Rugstad.
