occupancyData | R Documentation |
This data represnts truth with regards to occupancy in the simulated study
area. The probability of occupancy was simulated as pnorm(0, X
+ K alpha, 1, lower=FALSE)
, where K
and alpha
were constructed
from a reduced rank is an ICAR process with precision
(tau
) = 0.3 and gamma = c(-1, 0, 0, 1)
A data frame with 1600 observations on the following 5 variables.
Site labels
Longitude coordinate
Latitude coordinate
True probability of occupancy
The fixed effects portion of the occupancy process map
True realized occupancy
