LogTriangle distribution



Format: LogTriangle(
Min,Mode,Max)

 

 

 

Uses

The LogTriangle 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, Mode and Max parameters are defined such that:

VoseLogTriangle(Min, Mode, Max) = EXP(VoseTriangle(Min, Mode, Max))

 

ModelRisk functions added to Microsoft Excel for the LogTriangle distribution

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

VoseLogTriangleObject constructs a distribution object for this distribution.

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

VoseLogTriangleProb10 returns the log10 of the probability density or cumulative distribution function.

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

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

VoseLogTriangleFitP returns the parameters of this distribution fitted to data.
