Size Distributions for All Cities: Lognormal and q-exponential functions [PDF]
This paper analyses in detail the features offered by a function which is practically new to Urban Economics, the q-exponential, in describing city size distributions. We highlight two contributions.

Goodbye LogNormal Distribution
AbstractThe R-scripts presented and developed in the prior chapters assumed an investment return generating process that is both static and LogNormal, via the basic function. Indeed, had this work been done in the 1970s, or perhaps the 1670s when national (versus natural) tontines were first launched, that might have been sufficient.

Platoon Dispersion Analysis Based on Diffusion Theory
Urbanization and gro wing demand for travel, causes the traffic system to work ineffectively in most urban areas leadin g to traffic congestion. Many approaches have been adopted to address this problem, one among them being the signal co-ordination ...

Something New, Something Old: Parametric Models for the Size of Distribution of Income
Two new probability density functions (generalized beta and quadratic elasticity) are considered as models for the size distribution of income. The generalized beta distribution nests the generalized beta of the first and second kind, generalized gamma ...

Approximating the Sum of Correlated Lognormal or Lognormal-Rice Random Variables
A simple and novel method is presented to approximate by the lognormal distribution the probability density function of the sum of correlated lognormal random variables.

Inequality decomposition using the Gibbs output of a Mixture of lognormal distributions [PDF]
In this paper we model the income distribution using a Bayesian approach and a mixture of lognormal densities. The size of the mixture is determined by Chib (1995)'s method.

Some Composite ExponentialPareto Models for Actuarial Prediction [PDF]
Prediction is a very important and not so easy task for an actuary. An insurance company needs predictions of the future claims in order to evaluate premiums, to assess its financial situation, probabilities of ruin, etc.

Zipf's Law for Cities and the Double-Pareto-Lognormal Distribution [PDF]
This dissertation concentrates on the size distribution of cities. From an empirical perspective, it is shown that Zipf's law for cities holds for the upper tail of the distribution and that the overall distribution is the Double-Pareto-Lognormal ...
