The Exponential Distribution Introduction to Statistics

In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate. It is a particular case of the gamma distribution. It is the continuous analogue of the geometric distribution, … WebTo find the variance of the exponential distribution, we need to find the second moment of the exponential distribution, and it is given by: E [ X 2] = ∫ 0 ∞ x 2 λ e − λ x = 2 λ 2.
