peterson-tim-j/HydroState: Hidden Markov Modelling of hydrological state change

HydroState idenifies regime changes in streamflow runoff nor explained by varioations in precipitation. The package allows a flexible set of Hidden Markov Models of annual, seasonal or monthly streamflow runoff to be built that includes precipitation as a predictor of runoff. Suites of models can be build for a single site, ranging from from one to three states can be build and each with differing combinations of error models and auto-correlation terms, allowing the most parsimineous model (by AIC) to easily be idenified. The entire package is written in R S4 object oriented code. See Peterson TJ, Saft M, Peel MC & John A (2021), Watersheds may not recover from drought, Science, DOI: 10.1126/science.abd5085
