Occupancy in E-SURGE
Welcome to the 'Occupancy in E-SURGE' project. This is the Wiki page associated to the our paper Fitting occupancy models with E-SURGE: hidden Markov modelling of presence-absence data published in 2014 in Methods in Ecology and Evolution.
You will find here the ingredients to implement various occupancy models in program E-SURGE. We recommend you check Choquet (2008), Choquet et al. (2009) and the user's manual if you have any questions. Also, there's a FAQ site here. Otherwise, just email us.
To install E-SURGE 1.9.1, go here and follow the instructions.
- main features of E-SURGE
- single-season (static) models
- simplest static model
- incorporating heterogeneity via finite mixture on detection
- accomodating with multiple states and uncertainty
- dealing with multiple species
- multiple-season (dynamic) models
- simplest dynamic model
- incorporating the effect of a site-level covariate on extinction
- incorporating heterogeneity via a site random effect on extinction
- occupancy models with species misidentification (aka false positive errors)
- single- and multiple-season models, with random effects here
- published examples of occupancy models fitted in E-SURGE (check out the appendices for E-SURGE details)
