analysis.shi_bolt_confidence

seismostats.analysis.shi_bolt_confidence(magnitudes: ndarray, b: float, weights: ndarray | None = None, b_parameter: Literal['b_value', 'beta'] = 'b_value') → float

Returns the Shi and Bolt (1982) confidence limit of the b-value or beta.

Source:

Shi and Bolt, BSSA, Vol. 72, No. 5, pp. 1677-1687, October 1982

Parameters:

• magnitudes – Array of magnitudes.

• weights – Array of weights for the magnitudes.

• b – Known or estimated b-value/beta of the magnitudes.

• b_parameter – Either either ‘b_value’ or ‘beta’.

Returns:

std_b – Confidence limit of the b-value/beta value (depending on input).
