uniform (continuous) random variable


A random variableMathworldPlanetmath X is said to be a () random variable with parameters a and b if its probability density functionMathworldPlanetmath is given by

fX(x)=1b-a,x[a,b],

and is denoted XU(a,b).

Notes:

  1. 1.

    They are also called rectangular distributions, considers that all points in the interval [a,b] have the same mass.

  2. 2.

    E[X]=a+b2

  3. 3.

    Var[X]=(b-a)212

  4. 4.

    MX(t)=ebt-eat(b-a)t
