=VoseCombined({distributions},{weights},{names},U)

Constructs a new custom distribution of a number of different distributions. Use this function to model the opinions of different experts. Weights are assigned to each of the distributions, reflecting the relative confidence we have in them.

  • {distributions} - an array of distribution objects

  • {weights} - the weights assigned to each distribution. These should be proportional to the confidence you have in the individual estimates.

  • {names} - (optional) array with names for each distribution.

  • U - optional parameter specifying the cumulative percentile of the distribution. If omitted the function generates random values.

The function combines the distributions using the linear opinion pool method described in Stone (1961).
See Vose Combined Distribution window for an explanation about the ModelRisk window corresponding to this function.
