The characteristic function is a way for describing a random variable. The characteristic function, a function of t, completely determines the behavior and properties of the probability distribution of the random variable X. The characteristic function is similar to the cumulative distribution function, (where 1{X ≤ x} is the indicator function — it is equal to 1 when X ≤ x, and zero otherwise), which also completely determines the behavior and properties of the probability distribution of the rand…
