Four-parameter Beta distribution/PERT distribution #778
Comments
Thanks for the suggestion. Can you point us to any sampling algorithms for the distribution? |
Thanks! Question: why is this typically parameterised by I guess also it's common to use |
Mean is the average of all observations. Min/max values can be whatever. I'm generating customer demand data in XXX tons for example. And this can be from 0.1 ton to 10K ton. But (0,1) as default values are fine to me 🙂 |
Okay, I'll start on this soon, but it's currently blocked by #770. |
Background
What is your motivation?
Statistical computing.
What type of application is this? (E.g. cryptography, game, numerical simulation)
Simulation.
Feature request
Will be really nice to have four-parameter Beta distribution/PERT distribution in place. It offers an alternative to using the triangular distribution which takes the same parameters. The PERT distribution has a smoother shape than the Triangular distribution yielding extremes less frequently.
