%description
A suite of auxiliary functions that enhance time series estimation and
forecasting, including a robust anomaly detection routine based on Chen
and Liu (1993) <doi:10.2307/2290724> (imported and wrapped from the
'tsoutliers' package), utilities for managing calendar and time
conversions, performance metrics to assess both point forecasts and
distributional predictions, advanced simulation by allowing the generation
of time series components—such as trend, seasonal, ARMA, irregular, and
anomalies—in a modular fashion based on the innovations form of the state
space model and a number of transformation methods including Box-Cox,
Logit, 'Softplus-Logit' and Sigmoid.
