Love to see the progress in implementation of shape-restricted smooths in my favourite package! Shape-restricted smooths are great for constructing models reflecting theoretical assumptions and hypothesis testing in ecology. #rstats
A new release of the mgcv #RStats 📦 is out on CRAN and Simon Wood (U Edinburgh) has added some significant new features despite the small bump in version number:
🌟 scasm() for estimating GAMs with shape constrained smooths. Can be used with any family & smoothness selection is via the EFS method

Michal Man there, using the new device to #GoBelowground. We may need to come up with a new name for it--doesn't feel like a "mini" rhizotron.

První snímky z letos vyslané družice Biomass. Jako první satelit „vidí skrz stromy“ – dokážeme tak díky němu na dálku měřit množství dřevní hmoty a kvantifikovat množství uhlíku, který je v ní uložen.
🆕 The first stunning images from our groundbreaking #Biomass satellite mission have been released – they mark a major leap forward in our ability to understand how Earth’s forests are changing and exactly how they contribute to the global carbon cycle 🌳🌍
