datadata Triangular a

A description of a triangular distribution - a distribution whose PDF is a triangle ramping up from a lower bound to a specified midpoint and back down to the upper bound. This is a very simple distribution that does not generally occur naturally but is used sometimes as an estimate of a true distribution when only the range of the values and an approximate mode of the true distribution are known.

Constructors

Triangular
- triLower :: a
  The lower bound of the triangle in the PDF (the smallest number the distribution can generate)
- triMid :: a
  The midpoint of the triangle (also the mode of the distribution)
- triUpper :: a
  The upper bound of the triangle (and the largest number the distribution can generate)
