Widget Difference membuat sebuah time series stationary dengan cara menggantinya dengan 1st atau 2nd order discrete difference dari nilai-nilai-nya. Dalam bahasa matematika sederhana, widget Difference mengganti nilai time series input menjadi turunan pertama atau ke dua secara diskrit (digital).
Input
Time series: Time series as output by As Timeseries widget.
Output
Time series: Differences of input time series.
- Order of differencing. Can be 1 or 2.
- The shift before differencing. Value of 1 equals to discrete differencing. You can use higher values to compute the difference between now and this many steps ahead.
- Invert the differencing direction.
- Select the series to difference.
Untuk meng-integrasikan agar time series hasil widget Difference kembali ke nilai awal time series (misalnya, forecast), kita dapat menggunakan widget Moving Transform.
