A given Poisson phenomenon is characterized by a single parameter. From observed records this parameter may be estimated in at least two ways, namely by the mean and variance estimates from the sample, each computed from the observations. The efficiency of the variance estimate as compared with the mean estimate decays rapidly as the value of the parameter increases, and increases slowly with increasing sample sizes.
