Sets the control panel settings for use with the Calculate method.
Properties
Life Distribution
- 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).
- Subpopulations Sets the number of subpopulations in the mixed data set (mixed Weibull analysis only).
Control Panel Analysis Page Settings
- 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).
- SortBeforeCalculations Sets whether times-to-failure data will be sorted in ascending order before calculation.
- UngroupGroupedData Sets whether grouped data will be ungrouped when using rank regression.
- Weibull_UnbiasParameters Sets whether the biased beta estimate (due to MLE sampling error) will be corrected for the 2-parameter Weibull distribution.
Bayesian-Weibull Model Settings
- 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.
- Bayesian_MaxBeta Sets the maximum beta parameter to use for Bayesian-Weibull analysis when the assumed distribution is uniform.
- Bayesian_Results Sets whether the point estimates for beta are calculated from the median or mean value of the posterior distribution.
Application Setup Option
- UseSpecialSort Sets whether failures will always be put before suspensions when two identical times are encountered.
Usage Example
Declare a WeibullDataSet object.
Dim WDS as New WeibullDataSet
Set Weibull as the distribution for analysis.
WDS.AnalysisSettings.Distribution = WeibullSolverDistribution.Weibull
Specify that the 2-parameter version of the distribution will be used.
WDS.AnalysisSettings.Parameters = WeibullSolverNumParameters.MS_2Parameter
Set MLE as the method that will be used to estimate the parameters.
WDS.AnalysisSettings.Analysis = WeibullSolverMethod.MLE
