A method for estimating the local intensity of a one‐dimensional point process is described. The estimator uses an adaptation of Rosenblatt's kernel method of non‐parametric probability density estimation, with a correction for end‐effects. An expression for the mean squared error is derived on the assumption that the underlying process is a stationary Cox process, and this result is used to suggest a practical method for choosing the value of the smoothing constant. The performance of the… 
On Consistent Nonparametric Intensity Estimation for Inhomogeneous Spatial Point Processes
A common nonparametric approach to estimate the intensity function of an inhomogeneous spatial point process is through kernel smoothing. When conducting the smoothing, one typically uses events only
Intensity Estimation for Spatial Point Processes Observed with Noise
This article introduces a kernel estimator of the intensity function of spatial point processes taking into account location errors. The asymptotic properties of the estimator are derived and a
A quadrat neighborhood estimator for intensity function of point processes
In nonparametric estimation of the intensity function of a point process, assigning the local event weight is particularly important. This paper describes a sequential quadrat partitioning of the
A non-model-based approach to bandwidth selection for kernel estimators of spatial intensity functions
We propose a new bandwidth selection method for kernel estimators of spatial point process intensity functions. The method is based on an optimality criterion motivated by the Campbell formula
A tutorial on estimator averaging in spatial point process models
Assume that several competing methods are available to estimate a parameter in a given statistical model. The aim of estimator averaging is to provide a new estimator, built as a linear combination
Bayesian semiparametric intensity estimation for inhomogeneous spatial point processes.
A fully Bayesian semiparametric method to estimate the intensity of an inhomogeneous spatial point process, which provides inference regarding the dependence of the intensity function on possible covariates and uses information from the data to adaptively determine the amount of smoothing at the local level.
Bayesian nonparametric estimation of pair correlation function for inhomogeneous spatial point processes
The pair correlation function (PCF) is a useful tool for studying spatial point patterns. It is often estimated by some nonparametric approach such as kernel smoothing. However, the statistical
Equivalence of Smoothing Parameter Selectors in Density and Intensity Estimation
Abstract Kernel smoothing is an attractive method for the nonparametric estimation of either a probability density function or the intensity function of a nonstationary Poisson process. In each case
Bootstrap Confidence Regions for the Intensity of a Poisson Point Process
Abstract Bootstrap methods are developed for constructing confidence regions for the intensity function of a nonstationary Poisson process. Several different resampling algorithms are suggested,
Bootstrapping kernel intensity estimation for inhomogeneous point processes with spatial covariates
A consistent kernel estimator for the first-order intensity function based on covariates is constructed, which uses a convenient relationship between the intensity and the density of events location to derive the asymptotic bias and variance of the estimator.


Methods for Analysing Spatial Processes of Several Types of Points
Two approaches are described to the analysis of spatial patterns consisting of several types of points. The first approach uses a method of asymptotically unbiased estimation of the second moment
The spectral analysis of two-dimensional point processes
1. BASIC FORMULAE In a previous paper (Bartlett, 1963 b) I have developed in some detail statistical techniques for estimating and analysing the spectrum of a stationary point stochastic process in
Remarks on Some Nonparametric Estimates of a Density Function
1. Summary. This note discusses some aspects of the estimation of the density function of a univariate probability distribution. All estimates of the density function satisfying relatively mild
