LogUniform distribution



Format: VoseLogUniform(Min,Max, U)

LogUniform equations



Uses

The LogUniform is an approximate distribution, usually used in expert estimates, to describe a variable that may take a very wide range, e.g. max >10*min.

The Min and Max parameters are defined such that:

VoseLogUniform(Min, Max) = EXP(VoseUniform(Min, Max))

 

ModelRisk functions added to Microsoft Excel for the LogUniform distribution

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

VoseLogUniformObject constructs a distribution object for this distribution.

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

VoseLogUniformProb10 returns the log10 of the probability density or cumulative distribution function..

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

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

VoseLogUniformFitP returns the parameters of this distribution fitted to data.
