Changes in version 1.0.5 (2024-02-15) - Now, if the lags are automatically chosen, it is not allowed to use only one autoregressive lag with the additive ormultiplicative transformation (it does not make sense) Changes in version 1.0.4 (2023-03-24) - autoplot.grnnForecast has been modified to comply with CRAN Changes in version 1.0.3 - citation information has been added Changes in version 1.0.2 (2022-05-30) - References to the paper describing this package have been added in the documentation Changes in version 1.0.1 (2021-04-22) - The default transformation is now additive instead of multiplicative. Changes in version 1.0.0 (2021-03-08) - Automatic computation of smoothing parameter can be done with rolling origin or fixed origin (less accurate, but faster). - Lags can be selected using forward selection or backward elimination (feature selection techniques) - Time series cannot be scaled - The model is built using faster Rcpp code - An optional transformation to the training samples has been added. It improves forecast accuracy for time series with a trend Changes in version 0.2.0 - Uses Rcpp for speeding up computation of forecasts. Changes in version 0.1.0 (2019-11-25) - This is the first release of this package.
