In wiqid: Quick and Dirty Estimates for Wildlife Populations

Simulated detection/non-detection data for a fictitious species

Description

A data set for single-season occupancy modelling together with habitat covariates. See predictAvg for an example of its use.

Usage

data("toves")

Format

A data frame with detection (1) vs non-detection data for 2 species at 160 sites on three occasions.

y1, y2, y3, y4

detection histories for 4 occasions

x1, x2, x3

simulated habitat covariates

Source

Simulated data

Examples

data(toves)
str(toves)

# Extract detection histories
DH <- toves[, 1:4]

# Fit some models
m.1 <- occSS(DH, psi ~ x1, data=toves)
m.12 <- occSS(DH, psi ~ x1 + x2, data=toves)
m.13 <- occSS(DH, psi ~ x1 + x3, data=toves)
m.123 <- occSS(DH, psi ~ x1 + x2 + x3, data=toves)
m.23 <- occSS(DH, psi ~ x2 + x3, data=toves)
AICtable(AIC(m.1, m.12, m.13, m.123, m.23))
