WeibullAnalysisOptions Class

Sets the WeibullDataSet.AnalysisSettings property.

Syntax

• Distribution Sets the life distribution to fit to the data set.
• Parameters Sets the form of the selected life distribution (e.g., 2-parameter Weibull vs. mixed Weibull).
• Analysis Sets the method for estimating the parameters of the selected distribution (e.g., rank regression on X).
• RankingMethod Sets the method for calculating the unreliability estimates of the times-to-failure data (e.g., median ranks).
• UseRSRegression Sets whether the ReliaSoft ranking method (RRM) will be used to calculate the unreliability estimates for times-to-failure data.
• ConfBounds Sets the method for calculating the confidence bounds (e.g., Fisher Matrix).
• UngroupGroupedData Sets whether grouped data will be ungrouped when using rank regression.
• Subpopulations Sets the number of subpopulations in the mixed data set (mixed Weibull analysis only).
• Weibull_UnbiasParameters Sets whether the biased beta estimate (due to MLE sampling error) will be corrected for the 2-parameter Weibull distribution.
• Bayesian_PriorDistribution Sets the distribution to be used as the prior distribution of beta for Bayesian-Weibull analysis.
• Bayesian_Mean Sets the mean parameter to use for Bayesian-Weibull analysis when the normal distribution is assumed.
• Bayesian_Std Sets the standard deviation parameter to use for Bayesian-Weibull analysis when the normal distribution is assumed.
• Bayesian_Lambda Sets the lambda parameter to use for Bayesian-Weibull analysis when the exponential distribution is assumed.
• Bayesian_MinBeta Sets the minimum beta parameter to use for Bayesian-Weibull analysis when a uniform distribution is assumed.
