Silverman, Density Estimation for Statistics and Data Analysis. The variance (or bandwidth) σ 2 is the only parameter that needs to be estimated. The best bandwidth can be estimated using, for instance, the Silverman's rule.

Subjects Description Although there has been a surge of interest in density estimation in recent years, much of the published research has been concerned with purely technical matters with insufficient emphasis given to the technique's practical value. Furthermore, the subject has been rather inaccessible to the general statistician. The account presented in this book places emphasis on topics of methodological importance, in the hope that this will facilitate broader practical application of density estimation and also encourage research into relevant theoretical work. The book also provides an introduction to the subject for those with general interests in statistics. The important role of density estimation as a graphical technique is reflected by the inclusion of more than 50 graphs and figures throughout the text. Several contexts in which density estimation can be used are discussed, including the exploration and presentation of data, nonparametric discriminant analysis, cluster analysis, simulation and the bootstrap, bump hunting, projection pursuit, and the estimation of hazard rates and other quantities that depend on the density. This book includes general survey of methods available for density estimation. The Kernel method, both for univariate and multivariate data, is discussed in detail, with particular emphasis on ways of deciding how much to smooth and on computation aspects. Attention is also given to adaptive methods, which smooth to a greater degree in the tails of the distribution, and to methods based on the idea of penalized likelihood. Reviews "This well-written and moderately priced volume has removed any excuse for ignorance concerning density estimation on the part of applied statisticians; they will find the style refreshingly down-to-earth, and will value the clearsighted exposition. I thoroughly enjoyed reading it, and can recommend it wholeheartedly. Survey of Existing Methods. The Kernel Method for Univariate Data.

Estimation of heavy-tailed probability density function with application to Web data

Share Give access Share full text access. Share full text access. Density estimation requires answering two distinct questions. First, what is the best estimate for the underlying probability distribution?

Second, what do other plausible distributions look like? Ideally, one would like to answer these questions by first considering all possible distributions regardless of mathematical form , then identifying those that fit the data while satisfying a transparent notion of smoothness.

Such an approach should not require one to manually identify values for critical parameters, specify boundary conditions, or make invalid mathematical approximations in the small data regime.

However, the most common density estimation approaches, including kernel density estimation KDE [ 1 ] and Dirichlet process mixture modeling DPMM [ 6 , 7 ], do not satisfy these requirements. Previous work has described a Bayesian field theory approach, called Density Estimation using Field Theory DEFT [ 8 , 9 ], for addressing the density estimation problem in low dimensions.
