weibull module

Computation of tolerance intervals from a data-fitted Weibull distribution.

class gemseo.uncertainty.statistics.tolerance_interval.weibull.WeibullMinToleranceInterval(size, scale, shape, location)

Bases: WeibullToleranceInterval

Computation of tolerance intervals from a data-fitted Weibull distribution.

The formulae come from the R library tolerance [1].

Parameters:

• size (int) – The number of samples.

• scale (float) – The estimation of the scale of the Weibull distribution.

• shape (float) – The estimation of the shape of the Weibull distribution.

• location (float) – The estimation of the location of the Weibull distribution.
