%description
Implements functions and instruments for regression model building and its
application to forecasting. The main scope of the package is in variables
selection and models specification for cases of time series data. This
includes promotional modelling, selection between different dynamic
regressions with non-standard distributions of errors, selection based on
cross validation, solutions to the fat regression model problem and more.
Models developed in the package are tailored specifically for forecasting
purposes. So as a results there are several methods that allow producing
forecasts from these models and visualising them.
