%description
The main aim of this package is to combine the advantage of wavelet and
support vector machine models for time series forecasting. This package
also gives the accuracy measurements in terms of RMSE and MAPE. This
package fits the hybrid Wavelet SVR model for time series forecasting The
main aim of this package is to combine the advantage of wavelet and
Support Vector Regression (SVR) models for time series forecasting. This
package also gives the accuracy measurements in terms of Root Mean Square
Error (RMSE) and Mean Absolute Prediction Error (MAPE). This package is
based on the algorithm of Raimundo and Okamoto (2018) <DOI:
10.1109/INFOCT.2018.8356851>.
