Question:
What is the mean of this distribution?
What are the corresponding values of 1 and
2 for the equivalent beta distribution? According to the online help for the generalized beta distribution, its mean is min [1(1 2)] (max min). Does this evaluate to the same mean that you got for the PERT distribution? Finally, select the PERT distribution with parameters 4, 5, and 12 from @RISK’s Define Distributions window, and look at its shape and properties. Then select the equivalent BetaGeneral distribution with the parameters you found earlier.
Does it have the same shape and properties as the PERT distribution? It should—they are equivalent.
