Moment-based density estimation of confidential micro-data: a computational statistics approach

چکیده

Abstract Providing access to synthetic micro-data in place of confidential data protect the privacy participants is common practice. For be useful for analysis, it necessary that density function closely approximate data. Hence, accurately estimating based on sample important. Existing kernel-based, copula-based, and machine learning methods joint estimation may not viable. Applying multivariate moments’ problem sample-based has long been considered impractical due computational complexity intractability optimal parameter selection estimate when true unknown. This paper introduces a generalised form moment-based estimate, which can used functions only information empirical moments available. We demonstrate parametrisation solely by employing strategy selection. compare performance existing non-parametric parametric methods. The results show using provide reasonable, robust approximation comparable an example generation from resulting provides reasonable disclosure-protected alternative public release.

Anisotropic density growth of bone—A computational micro-sphere approach

Bones are able to adapt their local density when exposed to mechanical loading. Such growth processes result in densification of the bone in regions of high loading levels and in resorption of the material in regions of low loading levels. This evolution and optimisation process generates heterogeneous distributions of bone density accompanied by pronounced anisotropic mechanical properties. Wh...

A Computational Approach to Log-Concave Density Estimation

Non-parametric density estimation with shape restrictions has witnessed a great deal of attention recently. We consider the maximumlikelihood problem of estimating a log-concave density from a given finite set of empirical data and present a computational approach to the resulting optimization problem. Our approach targets the ability to trade-off computational costs against estimation accuracy...

A New Computational Approach to Density Estimation with Semidefinite Programming

Density estimation is a classical and important problem in statistics. The aim of this paper is to develop a new computational approach to density estimation based on semidefinite programming (SDP), a new technology developed in optimization in the last decade. We express a density as the product of a nonnegative polynomial and a base density such as normal distribution, exponential distributio...

Moment-Based Density Approximants

It is often the case that the exact moments of a statistic of the continuous type can be explicitly determined, while its density function either does not lend itself to numerical evaluation or proves to be mathematically intractable. The density approximants discussed in this article are based on the first n exact moments of the corresponding distributions. A unified semiparametric approach to...
