File List simulation.R figures.R redkite/model_monotonic.R redkite/plot_fun.R redkite/bva.Rda redkite/variables.csv redkite/XY.RdaDescription "simulation.R" : This file contains R codes to perform the following: Set up and perform simulations as described in the Appendix. "figures.R" : This file contains R codes to perform the following: Produce figures presented in the paper based on the models fitted using "modelfit_monotonic.R". "modelfit_monotonic.R" : This file contains R codes to perform the following: Model fitting for Red Kite breeding data, once with monotonic constraint and once unconstrained. "plot_fun.R" : This file contains R codes to perform the following: Plotting functions to be used in "figures.R". "bva.Rda", "variables.csv" : These files are R and csv data files: Red Kite breeding data for Bavaria and the variable description. "redkite/XY.Rda" : This file is an R data file: Data required for plotting purposes only. Rda files can be loaded into R as in R> load("bva.Rda")
