tick.preprocessing.LongitudinalSamplesFilter¶

class tick.preprocessing.LongitudinalSamplesFilter(n_jobs=-1)[source]¶

Longitudinal data preprocessor which filters out samples for which all

labels are null over the entire observation period.

Parameters

n_jobs : int, default=-1

Number of tasks to run in parallel. If set to -1, the number of tasks is set to the number of cores.
