Chapter 6. On the Parameter Estimation by Method of Moments and Wald Type Test for Poisson Processes
, 2018 We consider two statistical problems for inhomogeneous Poisson processes. The first one concerns the parameter estimation and the second one is about the goodness of fit test. We develop the method of moments in parameter estimation problem and describe the asymptotic behavior of the new test based on the method of moments estimator.
