A note on the average density function in urban analysis
It is argued that the density function, commonly used in the study of urban spatial structure, is more appropriately described as the ‘marginal density function’.

The average density of planar Brownian motion [PDF]
We show that the occupation measure on the path of a planar Brownian motion run for an arbitrary finite time intervalhas an average density of order three with respect to thegauge function t^2 log(1/t).

The average density of super-Brownian motion [PDF]
In this paper we prove the existence of average densities for the support of a superBrownian motion at a fixed time. Our result establishes a dimension-dependent fractal parameter for super-Brownian motion, which enables us to compare the local mass ...

AVERAGE DENSITY ESTIMATORS: EFFICIENCY AND BOOTSTRAP CONSISTENCY [PDF]
This paper highlights a tension between semiparametric efficiency and bootstrap consistency in the context of a canonical semiparametric estimation problem, namely the problem of estimating the average density. It is shown that although simple plug-in estimators suffer from bias problems preventing them from achieving semiparametric efficiency under ...

Not your average density [PDF]
GJK would like to thank T Alwyn Jones and Lars Liljas (Uppsala) for illuminating discussions and many pointers to relevant literature. RJR thanks Bart Hazes and Navraj S Pannu for stimulating discussions. We both thank our colleagues for allowing us to share unpublished results in the case histories.

BOOTSTRAPPING DENSITY-WEIGHTED AVERAGE DERIVATIVES [PDF]
We investigate the properties of several bootstrap-based inference procedures for semiparametric density-weighted average derivatives. The key innovation in this paper is to employ an alternative asymptotic framework to assess the properties of these inference procedures. This theoretical approach is conceptually distinct from the traditional approach (

ESTIMATING AVERAGE STEMWOOD DENSITY FROM BREAST HIGHT DENSITY IN THREE SPECIES OF FOREST TREES [PDF]
Simple regression was used to obtain a mathematical equations for estimating the total stemwood density in three species of forest tree, namely: Pinus brutia Ten, Casuarina equestifolia, and Eualyptus Camaldulensis Dehn; by connecting the total stemwood ...

Averaging population density [PDF]
Abstract Population density is a commonly quoted statistic. Almost no general descriptive summary of the population of an area is complete without a density listing, table or map. As each such density statistic is an average, it is worth considering what kind of average is being used. This article analyzes this and illustrates the effect
