cTSI (coastal trophic state index) contains data and code used in development and application of a Bayesian Proportional Odds Logistic Regression model to classify sites according to water quality variables related to trophic state.
The code includes several R markdown files and an associated file containing R functions. The main body of code coastal_TSI_ts.Rmd loads the function file located in the functions folder. Raw data is included as .csv files in the raw directory and various data sets created as intermediate products are in the data folder. Variable definitions are included in a data dictionary
The code has been used to generate the analysis reported in
Hagy, J. D., B. J. Kreakie, M. C. Pelletier, F. Nojavan, J. A. Kiddon and A. J. Oczkowski (2022). "Quantifying coastal ecosystem trophic state at a macroscale using a Bayesian analytical framework." Ecological Indicators 142. https://doi.org/10.1016/j.ecolind.2022.109267
