Pseudo-jackknife estimators for a hyperbinomial process

C. Ferreri & M. R. Ferrante
The instability problem of both the maximum likelihood (MLE) and moment method (MME) estimators of the process-index of a hyperbinomial process (HBP) is reconsid-ered coherently with the phenomenical view justifying the choice of the model. Hence, some pseudo-jackknife and graduation procedures are indicated allowing one to attenu-ate instability effects due to both minor fluctuations in the right-tail of a frequency distribution and changes of dispersion type. An example is given in order to illustrate also...
