Terapkan fungsi rolling window ke time series. Gunakan widget Moving Transform untuk mendapatkan rata-rata nilai dari series.
Input
Time series: Time series as output by As Timeseries widget.
Output
Time series: The input time series with the added series’ transformations.
Dalam widget Moving Transform, kita dapat menentukan fungsi agregasi apa yang harus dijalankan dalam time series dan dengan ukuran windows berapa.
- Define a new transformation.
- Remove the selected transformation.
- Time series you want to run the transformation over.
- Desired window size.
- Aggregation function untuk meng-agregate nilai di windows. Opsi yang ada adalah: mean (rata-rata), sum (jumlah), max, min, median, mode, standard deviation, variance, product, linearly-weighted moving average, exponential moving average, harmonic mean, geometric mean, non-zero count, cumulative sum, dan cumulative product.
- Select Non-overlapping windows options if you don’t want the moving windows to overlap but instead be placed side-to-side with zero intersection.
- In the case of non-overlapping windows, define the fixed window width(overrides and widths set in (4).
Example
Pada widget Moving Transform untuk memperoleh 5-day moving average, kita dapat menggunakan rolling window dengan mean aggregation.
Pada widget Moving Transform, untuk mengintegralkan time series’ difference dari widget Difference, gunakan Cumulative sum aggregation pada window yang cukup lebar untuk menangkap keseluruhan series.
