WebCumulative Distribution Function ("c.d.f.") The 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 ... WebMar 9, 2024 · Cumulative Distribution Functions (CDFs) Recall Definition 3.2.2, the definition of the cdf, which applies to both discrete and continuous random variables. For continuous random variables we can further specify how to calculate the cdf with a formula as follows. Let \(X\) have pdf \(f\), then the cdf \(F\) is given by ...
