  1. The negative binomial distribution

    Bartko, John JaroslavVirginia Polytechnic Institute1960

    … review of the major literature dealing with the negative binomial distribution. An account of the forms of the distribution is presented. This includes compound, limiting and truncated forms and examples of their occurrence. Parameter estimation is treated in a few specific cases. In particular, …

This approach takes the decision of prior selection out of the hands of the researcher. Ideally, …
