This page describes random distributions supported by Filebench

Uniform Distribution

DOMAIN: [a;b]

PDF: <math> f(x; a, b) = {1 \over {b - a}} </math>

CDF: <math> F(x; a, b) = {x - a \over {b - a}} </math>

EXPECTED: <math> (b - a) \over 2 </math>


Exponential Distribution

DOMAIN: <math> [0:\infty) </math>

PDF: <math> f(x; \lambda) = \lambda e^{-\lambda x} </math>

CDF: <math> F(x; \lambda) = 1 - e^{-\lambda x} </math>

EXPECTED: <math> 1 \over \lambda </math>
