What is DENSITY ESTIMATION ?Theprobability DENSITY functionis a fundamental concept in STATISTICS . Consider any random quantityXthat has probabilitydensity functionf. Specifying the functionfgives a natural description of the distribution ofX, and allows probabilitiesassociated withXto be found from the relationSuppose, now, that we have a set of observed data points assumed to be a sample from an unknown probability DENSITY , as discussed in this book, is the construction of an estimate of the DENSITY function from the observed two main aims of the book are to explain how to estimate a DENSITY from a given data set and to explore how densityestimates can be used, both in their own right and as an ingredient of other statistical approach to DENSITY estim

Density estimation, as discussed in this book, is the construction of an estimate of the density function from the observed data. The two main aims of the book are to explain how to estimate a density from a given data set and to explore how density estimates can be used, both in their own right and as an ingredient of other statistical procedures.
