RiskPert

Description
|
RiskPert(minimum, m.likely, maximum) specifies a PERT distribution with specified minimum, most likely, and maximum values. The PERT distribution (meaning Program Evaluation and Review Technique) is similar to a triangular distribution in that it has the same set of easily understandable parameters, but it might be preferred to the triangular distribution because of its curved density. Technically, it is a special case of the BetaGeneral) distribution.

Examples

RiskPert(0,2,10) returns a PERT distribution with minimum 0, maximum 10, and most likely value 2. RiskPert(A1,A2,A3) specifies a PERT distribution with its three parameters taken from the cells A1, A2, and A3.
