Occ.OD: Analyzes Occupancy data using the Occupancy/Detection model

Description Usage Arguments

Description

Uses Mackenzie's Occupancy/Detection model.

Usage

1
2
3
Occ.OD(Y, Covariate.data = NULL, Occupancy.formula = ~1,
  Detection.formula = ~1, n.chains = 4, n.adapt = 1000, n.iter = 1000,
  num.cores = 1, fit = NULL, inits = NULL)

Arguments

Y

A data frame with 5 columns - Species, Site, Observer, Effort, NumDetections

Covariate.data

Data frame with the same number of rows as Y

Occupancy.formula

Model formula specifying the relationship between Occupancy and the covariates

Detection.formula

Model formula specifying the relationship between Detection probability and the covariates

n.chains

How many MCMC chains to fit.

n.adapt

How long should the burn-in phase be.

n.iter

How many samples to take after the burn-in.

num.cores

How many computer cores to use.

inits

Initial values for the model chains.

N.limit

Maximum conceivable number of individuals at a site. Making this too large slows down the model fitting, though.
