A common functional relationship among Lotka's law, Bradford'slaw, and Zipf's law is derived and takes explicit account of the sequences of observed values of the variables by means of an index, which results in a more realistic and precise formulation of each law.

A rigorous analysis of Bradford's law is made using an index for the observed values of the variables, and the shape of Bradford-type curves can be described in terms of three distinct regions and two shape parameters.

The use of Zipf's law in the screening of analytical data: a step beyond Benford.

This study shows for the first time the effectiveness of Zipf's law in screening analytical data sets for outliers, data formatting and data transcription errors, particularly when the data sets are…

The Simon-Yule Approach to Bibliometric Modeling

A frequency distribution function derived from a stochastic model considering human behaviors and its comparison with an empirical bibliometric distribution

Simon's stochastic model is extended to take both ‘selective’ and ‘random’ factors in human behaviors into consideration. The resulting distribution function is of ‘non-steadystate’ type and…

Lotka and Zipf: Paper dragons with fuzzy tails

A linear correlation exists between the Lotka frequency and Zipf rank distribution functions and these results show that information distributions are not homogeneous and cannot be completely described by two parameter functions.

This paper proves a statistical relationship which links two types of productivity distributions, size‐frequency and rank‐frequency, which can be estimated given the number of journals and references.

Patterns of Scientific Productivity and Social Change: A Discussion of Lotka's Law and Bibliometric Symmetry

This paper examines the application of symmetry principles to bibliometric laws, using Lotka's law for illustration, and it is shown that the function occurring in Lotka’s law is essentially the only one with desireable properties that is consistent with the symmetry constraint.

THEORY OF THE BRADFORD LAW

The Bradford law is explored theoretically by means of a very mixed Poisson model which, it is claimed, elucidates the uncertainties surrounding the law and its applications. It is argued that…

A general theory of bibliometric and other cumulative advantage processes

It is shown that such a stochastic law is governed by the Beta Function, containing only one free parameter, and this is approximated by a skew or hyperbolic distribution of the type that is widespread in bibliometrics and diverse social science phenomena.

THE DERIVATION AND APPLICATION OF THE BRADFORD‐ZIPF DISTRIBUTION

The present paper shows that the Bradford distribution is closely related to the Zipf distribution, which requires data on only the most productive journals, is mathematically simple and amenable to graphical methods if a proposed idea of the ‘completeness’ of a search is accepted.

Technical Note - Exact Solution for the Bradford Distribution and Its Use in Modeling Informational Data

This work develops simple tests to see how well a given sample of data conforms to one or the other distribution and applies the tests to two samples; the number of operations research articles appearing in various journals in a given time interval and the rate of use of various physics periodicals in a science library.

THE BRADFORD DISTRIBUTION

The model is derived from S. C. Bradford's ‘law of scattering’ and is called the Bradford Distribution and is used to predict the reference yield of abstracting journals in a search for thermophysical property data.
