relife.datasets.load_insulator_string() relife.data.LifetimeData[source]

Load and return the insulator string lifetime data for regression.

The data were simulated from a real estimate:

  • time: time-to-event or durations in years,

  • event: if a failure occurs during the observation period,

  • entry: age of the circuit breakers in years at the beginning of the observation period,

  • args: tuple of covariates related to the atmospheric polluants.

Returns

The lifetime data as a dataclass instance.

Return type

LifetimeData

Examples

import numpy as np
from scipy.stats import boxcox, zscore
from relife.datasets import load_circuit_breaker
time, event, entry, *args = load_insulator_string().astuple()
covar = zscore(np.column_stack([boxcox(col)[0] for col in args[0].T]))
