Thus, for example, if X is distributed as a Poisson random variable with parameter [lambda] being [[mu].sub.x] = [[sigma].sup.2.sub.x] = [lambda], we obtain that the function f(x) = [[integral].sup.x] k[[lambda].sup.-1/2]d[lambda] = [k.sup.*] [square root of x]...

That is, test the hypothesis = 0 against 0. If one assumes that X t is normally distributed, standard linear regression techniques apply. This paper investigates the robustness of the standard F test on when X t is, in fact, Poisson-distributed with mean ± + t.doi:10.1080/...
If {Sn; n≥ 1} is a sequence of independent random variables distributed according to the exponential law of parameter λ = 1, then, for all α > 0, the integer random variable [6] N=inf{S1+⋯+Sn+1>α;n≥1} follows the Poisson law with parameter α. • mathematical expectation...
