dqa.tasks.time_series.ConstantValuesIntervals#
- class dqa.tasks.time_series.ConstantValuesIntervals(timestamp_name: str, interval_start: str, interval_end: str, value: Any, min_time: float, **kwargs)#
Returns a list of intervals in which a time series has a specified constant value.
The input time series is given as input_name (first entry). Each resulting interval must have a certain minimum length, needs to contain at least two data points and the input time series needs to be constant with a specified value on it.
- Parameters:
timestamp_name (str) – The timestamp data row.
interval_start (str) – Name of the output data row containing the start times of the intervals.
interval_end (str) – Name of the output data row containing the end times of the intervals.
value (any) – The constant value the time series needs to have on the intervals.
min_time (float) – The minimal length of an interval to be detected.
Methods
