"WebThe cumulative distribution function (" c.d.f.") of a continuous random variable X is defined as: F ( x) = ∫ − ∞ x f ( t) d t. for − ∞ < x < ∞. You might recall, for discrete random variables, that F ( x) is, in general, a non-decreasing step function. For continuous random variables, F ( x) is a non-decreasing continuous function.

Cumulative vs probability density

WebIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample … WebAt each t, fX(t) is the mass per unit length in the probability distribution. The density function has three characteristic properties: (f1) fX ≥ 0 (f2) ∫RfX = 1 (f3) FX(t) = ∫t − ∞fX. A random variable (or distribution) which has a density is called absolutely continuous. This term comes from measure theory.
