WEBMar 16, 2024 · A cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. CDFs have the following definition: CDF(x) = P(X ≤ x)

WEBThe cdf of random variable \(X\) has the following properties: \(F_X(t)\) is a nondecreasing function of \(t\), for \(-\infty<t<\infty\). The cdf, \(F_X(t)\), ranges from 0 to 1. This makes sense since \(F_X(t)\) is a probability. If \(X\) is a discrete random variable whose minimum value is \(a\), then \(F_X(a)=P(X\le a)=P(X=a)=f_X(a)\).

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.
