Web1 apr 2024 · From supporting wood production to mitigating climate change, forest ecosystem services are crucial to the well-being of humans. Understanding the mechanisms that drive forest dynamics can help us infer how to maintain forest ecosystem services and how to improve predictions of forest dynamics under climate change. Despite the … WeblessSEM lessSEM (lessSEM estimates sparse SEM) is an R package for regularized structural equation modeling (regularized SEM) with non-smooth penalty functions (e.g., lasso) building on lavaan. lessSEM is heavily inspired by the regsem package and the lslx packages that have similar functionality. If you use lessSEM, please also cite regsem …
