| Title: | Seasonal Adjustment of High Frequency Data with 'JDemetra+ 3.x' |
|---|---|
| Description: | R Interface to 'JDemetra+ 3.x' (<https://github.com/jdemetra>) time series analysis software. It provides functions for seasonal adjustment of high-frequency data displaying multiple, non integer periodicities. Pre-adjustment with extended airline model and Arima Model Based decomposition. |
