Split Triangle distribution



SplitTriangle(low,medium,high,lowP,mediumP,highP)

 

Uses

The SplitTriangle is used to model expert opinion where the SME is asked for three points on the distribution: for each point the SME provides a value of the variable and their view of the probability of being less than that value. The SplitTriangle then extrapolates from these values to create a distribution composed of 2 triangles as in the figure above.

ModelRisk functions added to Microsoft Excel for the Split-Triangle distribution

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

VoseSplitTriangleObject constructs a distribution object for this distribution.

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

VoseSplitTriangleProb10 returns the log10 of the probability density or cumulative distribution function.
