I'm not sure how, but I almost completely forgot I did this in #phytools even though it was only, like, two weeks ago: "A Pagel '94 type correlation model with one binary trait and one continuous character" using the discretized diffusion approximation (blog.phytools.org/2025/07/a-page…).

I'm organizing an #Evol2025 meet-up run tomorrow (Sunday) at 6:15am. All ability levels & we'll do an out-and-back -- so no chance of getting lost. Meeting outside the Classic Center. Please email me if you want more details, or just show up!

This seems like a good postdoc with @MartBulla & Prague would be cool. More info: researchgate.net/job/1021667_Po…. RT & share.
