Conventional parametric count distributions, namely the Poisson and Negative-Binomial models, do not offer satisfactory descriptions of empirical distributions of completed cohort parity. One reason is that they cannot model variance-to-mean ratios below unity, that is, underdispersion, which is...

Generalizing Brookes theoretical explorations of the Bradford law (J. DOC. 33 (1977) 180) and searching for law-like hypotheses (J. Quant. Linguistics 6 (1999) 188) in linguistics and musicology led to a new type of partial-sums distributions. Some properties of this class of distributions are...
