Triangular Distribution |
(continuous probab dist for equations) |
Usage: |
TriangularDist (x, m, w) |
Definition: |
(w - |x - m|) / w^2 |
Required: |
w > 0 |
Support: |
m-w ⋜ x ⋜ m+w |
Moments: |
μ = m σ = w / sqrt (6) γ1 = 0 β2 = 2.4 |
The graph of this distribution has a triangular shape, with the highest point at x = a, and nonzero values from a - w to a + w.
