Population distribution function

WebThe probability density function (" p.d.f. ") of a continuous random variable X with support S is an integrable function f ( x) satisfying the following: f ( x) is positive everywhere in the support S, that is, f ( x) > 0, for all x in S. The area under the curve f ( x) in the support S is 1, that is: ∫ S f ( x) d x = 1. WebThe ICDF is the reverse of the cumulative distribution function (CDF), which is the area that is associated with a value. For all continuous distributions, the ICDF exists and is unique if 0 < p < 1. When the probability density function (PDF) is positive for the entire real number line (for example, the normal PDF), the ICDF is not defined for either p = 0 or p = 1.
