Cumulative density function example
WebA cumulative density function (CDF) gives the probability that X is less than or equal to a value, say x. A CDF is usually written as F ( x) and can be described as: F X ( x) = P ( X ≤ x) I like to subscript the X under the function name so that I know what random variable I'm processing.
