occstanhm: Hierarchical occupancy models with correlated error structure

This repository contains a R package with 2-level and 3-level occupancy models.
The package also contains a set of tutorials designed to help users understand how to use and code occupancy models in Stan.
The models include a statistical hierarchy that allows for
multi-species modeling and estimating correlations among species.
The models may also be used as a more general "random-effect" type
occupancy model. The models are written in Stan and called through R. The cmdstanr package is used, rather than the more common rstan
package, because features used in Stan were not supported by rstan
at the time of development.
Additionally, cmdstanr allows for quicker performance than rstan.
