Let $\struct {\Omega, \Sigma, \Pr}$ be a probability space.
Let $X$ be a discrete random variable on $\struct {\Omega, \Sigma, \Pr}$.
Absolute
The absolute cumulative frequency of $X$ is defined as:
- $\forall x \in \Dom X: \map {\text {acf} } x = \ds \sum_{y \mathop \le x} \map \Omega y$
Relative
The relative cumulative frequency of $X$ is defined as:
- $\forall x \in \Dom X: \map {\text {acf} } x = \dfrac {\ds \sum_{y \mathop \le x} \map \Omega y} {\size {\Dom X} }$
