compute_threshold#

pymovements.events.detection.microsaccades.compute_threshold(arr: ndarray, method: str = 'engbert2015') → ndarray[source]#

Determine threshold by computing variation.

The following methods are supported:

  • std: This is the channel-wise standard deviation.

  • mad: This is the channel-wise median absolute deviation.

  • engbert2003: This is the threshold method as described in [Engbert et al., 2003].

  • engbert2015: This is the threshold method as described in [Engbert et al., 2015].

Parameters:

  • arr (numpy.ndarray) – Array for which threshold is to be computed.

  • method (str) – Method for threshold computation. (default: ‘engbert2015’)

Returns:

Threshold values for horizontal and vertical direction.

Return type:

numpy.ndarray

Raises:

ValueError – If passed method is not supported.
