摘要：

Let fo(x) be the exponential density and f(gamma)(x) the translation model. Let (X-i)(i=1,n) be i.i.d. random variables, with density g. We test that g is f(0) against g is a simple mixture, using the LRT statistic. We prove that the LRT diverges to infinity with probability 1/2 and it is equal to 0 with probability 1/2. Therefore, the classical likelihood limiting theory does not hold.
