Pyaf 5.0 Final Touch 7 : Improve the Guess of Window Length for Moving Average Trends

[antoinecarme]

Moving Average and Moving Median Trends are using windows of variable lengthds. These lengths are by default

https://github.com/antoinecarme/pyaf/blob/4ab4a659801ba2d48ca519f605d6d97754879922/pyaf/TS/Options.py#L223

These lengths can be customized according to the time resolution detected in the dataset. A daily signal can have [5, 7, 30] windows (business week , week, month). An hourly signal can have [12, 24] (half-day, day) windows.

The user choice, of course, will override this setting.

This issue only impacts slow modeling processes. Will not have impact by default.

Model Trend Explainability improves.

New settings by default

    def get_moving_window_lengths_for_time_resolution(self, iResolution):
        # self.mOptions.mMovingAverageLengths self.mOptions.mMovingMedianLengths 
        lWindows = {}
        lWindows[eTimeResolution.SECOND] = [60] # Minute
        lWindows[eTimeResolution.MINUTE] = [60] # Hour
        lWindows[eTimeResolution.HOUR] = [12, 24] # Half-Day, Day
        lWindows[eTimeResolution.DAY] = [5, 7, 30] # Business Week, Week, Month
        lWindows[eTimeResolution.MONTH] = [3, 6, 12] # 3, 6 and 12 months
        return lWindows.get(iResolution , [])
