weibullness (version 1.23.8)

Goodness-of-Fit Test for Weibull Distribution (Weibullness)

Description

Performs a goodness-of-fit test for Weibull distribution (weibullness test) and provides the parameter estimates of the two- and three-parameter Weibull distributions. Note that the threshold parameter is estimated based on the correlation from the Weibull plot. For more details, see , , and . This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIT) (No. 2022R1A2C1091319, RS-2023-00242528).
