File descriptions

Data files

data/ga_bear_data_females.gzip

• Compressed R data file with the encounter histories, trap coordinates, and trap operational status information.

data/state-space360.tif

• GeoTiff spatial layer defining the state space.

R scripts

R/sstats_maps.R

• Compute summary statistics and create maps of the detection locations, referenced by year, for each bear.

R/fit.R

• Fit the model with the lowest WAIC score. The other models were run on the UGA cluster. That code is not included here.

• Warning It takes about a day to run this script.

R/forecast.R

• Forecast with the fitted model. Depends on the forecast function in R/forecast_fn.R

• Warning It takes about a day to run this script.

R/forecast_fn.R

• Function for forecasting population dynamics.

R/testS.R

• Assess sensitivity of results to specification of the state space.

JAGS model

R/dT-s0-rPDD2-phi0-pYB-sig0.jag

• The most supported model.
