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) Where X is … See more Cumulative distribution functions are excellent for providing probabilities that the next observation will be less than or equal to the value you specify.
