Estimators and variance estimators tailored to the NILS hierarchical design (Adler et al. 2020, < https://res.slu.se/id/publ/105630>; Grafström et al. 2023, < https://res.slu.se/id/publ/128235>). The National Inventories of Landscapes in Sweden (NILS) is a long-term national monitoring program that collects, analyses and presents data on Swedish nature, covering both common and rare habitats < https://www.slu.se/om-slu/organisation/institutioner/skoglig-resurshushallning/miljoanalys/nils/>.
This repo contains an R-package which provides design-based estimators and variance estimators used in the NILS-programs. NILS is an acronym for the National Inventories of Landscapes in Sweden, a group of environmental monitoring programs governed by the Swedish University of Agricultural Sciences (SLU).
