%description
Identifies regime changes in streamflow runoff not explained by variations
in precipitation. The package builds a flexible set of Hidden Markov
Models of annual, seasonal or monthly streamflow runoff with precipitation
as a predictor. Suites of models can be built for a single site, ranging
from one to three states and each with differing combinations of error
models and auto-correlation terms. The most parsimonious model is easily
identified by AIC, and useful for understanding catchment drought
