pyhctsa.operations.stationarity.range_evolve(y)

Analyze how the time-series range changes across time.

This operation measures the range (peak-to-peak) of the time series as a function of time by calculating range(x_{1:i}) for i = 1, 2, …, N, where N is the length of the time series. It provides insights into how new extreme events emerge over time.

Parameters:
y : array-like

The input time series to analyze

Returns:

Dictionary containing various metrics about range evolution.

Return type:

Dict[str, float]
