CRAN: Package SightabilityModel

SightabilityModel: Wildlife Sightability Modeling

Uses logistic regression to model the probability of detection as a function of covariates. This model is then used with observational survey data to estimate population size, while accounting for uncertain detection. See Steinhorst and Samuel (1989).
