Robust design salamander occupancy data
A robust design occupancy data set for modelling presence/absence data for salamanders.
A data frame with 40 observations (sites) on the following 2 variables.
a character vector containing the presence (1) and absence (0) with 2 primary occasions with 48 and 31 visits to the site
frequency of sites (always 1)
This is a data set that I got from Gary White which is suppose to be salamander data collected with a robust design.
