In stocc: Fit a Spatial Occupancy Model via Gibbs Sampling

Description

This data represents a simulated study area. The study area is a 40 x 40 grid of pixels. There are two variables, a factor variable (e.g., a habitat layer), as well as, a continuous covariate.

Format

A data frame with 1600 observations on the following 5 variables.
