WeibullGeneralOptions

• WeibullGeneralOptions Weibull solver general options
• WarnNegLocation Whether to generate a warning if location parameter is negative.
• WeibullGeneralOptions.DiscardNegLocation For rank regression, resets location parameter to 0. For MLE finds the maximum in the possible domain.
• WeibullGeneralOptions.ResetExpLocation For exponential distribution with rank regression, if the location parameter is greater than the first time-to-failure (T1), it is reset to T1.
• WeibullGeneralOptions.Use3PTrueMLE Whether to use a full MLE solution on 3-parameter Weibull.
• WeibullGeneralOptions.UseExtendedGGamma If set to true, allows the Lambda parameter in the Generalized Gamma distribution to be negative.
• WeibullGeneralOptions.AllowBiasingNormal If set to true and using normal distribution (complete data only), corrects the MLE Std (sigma) for biasedness.
• WeibullGeneralOptions.UsePlottedYPoints If set to true, uses computed plot points in obtaining D for Kolmogorov-Smirnov test.
