Summarise Pert probability distributions for specified minimum, mode and maximum values

Input Distribution parameters

This utility calculates summary values for a Pert distribution for specified values for minimum, mode and maximum values.

Inputs are the required minimum, mode, maximum values and a shape parameter for the desired distribution and the required number of digits after the decimal point in the output. The shape parameter determines the degree of concentration of the distribution around the mode. The (commonly used) default value is 4. Larger values result in greater concentration around the mode, while smaller values result in concentration towards the tails.

Outputs are a table of percentiles, mean and mode and a density curve for the specified distribution.
