The first supplement (Worked example of model fitting for theJena_dataset.pdf) provides a detailed description of the application and interpretation of a range of models using the Jena dataset. The second and third supplements (SAS code for analysis of Jena_dataset.sas) and (R code for analysis of Jena_dataset.r) provide SAS and R code to implement the method using the Jena dataset. The data for the two sites is provided in Jena_data.csv and Ireland_site_biodepth.csv.
