WebThe formula for the exponential distribution: P (X = x) = m e-m x = 1 μ e-1 μ x P (X = x) = m e-m x = 1 μ e-1 μ x Where m = the rate parameter, or μ = average time between occurrences. We see that the exponential is the cousin of the Poisson distribution and they are linked through this formula.
