continuous density function


Let X be a continuous random variable. The function fX:[0,1] defined as fX(x)=FXx, where FX(x) is the cumulative distribution functionMathworldPlanetmathPlanetmathPlanetmath (http://planetmath.org/CumulativeDistributionFunction) of X, is called the continuous density function of X. Please note that if X is a continuous random variable, then fX(x) does not equal P[X=x]; for more information read the article on cumulative distribution functions.

Analogously to the discrete case, this function must satisfy:

  1. 1.

    fX(x)0 for all x

  2. 2.

    xfX(x)𝑑x=1
