%description
Functions and wrappers for using the Multiple Aggregation Prediction
Algorithm (MAPA) for time series forecasting. MAPA models and forecasts
time series at multiple temporal aggregation levels, thus strengthening
and attenuating the various time series components for better holistic
estimation of its structure. For details see Kourentzes et al. (2014)
<doi:10.1016/j.ijforecast.2013.09.006>.
