%description
An engine for univariate time series forecasting using different
regression models in an autoregressive way. The engine provides an uniform
interface for applying the different models. Furthermore, it is extensible
so that users can easily apply their own regression models to univariate
time series forecasting and benefit from all the features of the engine,
such as preprocessings or estimation of forecast accuracy.
