The PERT distribution is a family of continuous distributions give the minimum (a), most likely (b) and maximum (c) values that a variable can take.   Click to see graphs.  PERT-distributions-by-mode.png

It is a transformation of the four-parameter Beta distribution. The modified-PERT introduces a fourth parameter, lamda, that controls how peaked the distribution is, or conversely how much probability is in the tails.  See example graphs  PERT-distributions-by-peakedness-lamda.png

Analytica has the beta distribution built-in. We have added the modified PERT as a distribution function in the attached library.

Download Free Analytica


    We hate spam as much as you. We won't share your email with third parties.
    The free edition of Analytica includes these key Analytica features:
    • intuitive visual modeling with influence diagrams
    • the convenience and power of Intelligent Arrays
    • managing risk and uncertainty with fast Monte Carlo
    • sharing models on the web with the Analytica Cloud Platform (ACP)
    Free Analytica has no time limit. The only constraint is it won’t let you create more than 100 variables or other objects. But your model can be quite substantial since each variable can be a multidimensional array. It also lets you explore, change inputs, and run existing models of any size (excluding features unique to the Enterprise or Optimizer editions).
    • Analytica runs on any Windows computer, or on a Macintosh using Parallels or VMWare. ACP runs via any web browser.
