Three-parameter Weibull distribution


Format: Weibull3(α,β,θ)

 

The Weibull3 distribution is a Weibull distribution shifted θ along the x-axis, so that:

      
        

 

ModelRisk functions added to Microsoft Excel for the Three-Parameter Weibull distribution

VoseWeibull3 generates random values from this distribution for Monte Carlo simulation, or calculates a percentile if used with a U parameter.

VoseWeibull3Object constructs a distribution object for this distribution.

VoseWeibull3Prob returns the probability density or cumulative distribution function for this distribution.

VoseWeibull3Prob10 returns the log10 of the probability density or cumulative distribution function.

VoseWeibull3Fit generates values from this distribution fitted to data, or calculates a percentile from the fitted distribution.

VoseWeibull3FitObject constructs a distribution object of this distribution fitted to data.

VoseWeibull3FitP returns the parameters of this distribution fitted to data.
