%description
The wavelet and ANN technique have been combined to reduce the effect of
data noise. This wavelet-ANN conjunction model is able to forecast time
series data with better accuracy than the traditional time series model.
This package fits hybrid Wavelet ANN model for time series forecasting
using algorithm by Anjoy and Paul (2017) <DOI: 10.1007/s00521-017-3289-9>.
