- Dataset.pos2acc(*, degree: int = 2, window_length: int = 7, padding: str | float | int | None = 'nearest', verbose: bool = True) Dataset #
Compute gaze accelerations in dva/s^2 from dva coordinates.
This method requires a properly initialized
experiment
attribute.After success, the gaze dataframe is extended by the resulting acceleration columns.
- Parameters:
degree (int) – The degree of the polynomial to use. (default: 2)
window_length (int) – The window size to use. (default: 7)
padding (str | float | int | None) – The padding method to use. See
savitzky_golay
for details. (default: ‘nearest’)verbose (bool) – If True, show progress of computation. (default: True)
- Returns:
Returns self, useful for method cascading.
- Return type:
- Raises:
AttributeError – If gaze is None or there are no gaze dataframes present in the gaze attribute, or if experiment is None.
