A Transformation-Based Nonparametric Estimator of Multivariate Densities with an Application to Global Financial Markets

SSRN Electronic Journal, 2011
We propose a probability-integral-transformation-based estimator of multivariate densities. Given a sample of random vectors, we rst transform the data into their corresponding marginal distributions. We then estimate the density of the transformed data via the Exponential Series Estimator in Wu (2010).

Nonparametric method for estimating spoken language sound multivariate probability density function

2008 Microwaves, Radar and Remote Sensing Symposium, 2008
In the paper a new approach for estimating of the spoken language sound multivariate probability density is suggested. It is based on the use of a projection of a random process to the set of random variables, with the probability density defined as a product of two-dimensional densities.

A Note on Asymptotic Behavior of the Nonparametric Density Estimators in Multivariate Mixtures

Communications in Statistics - Theory and Methods, 2009
The asymptotic behavior of the nonparametric density estimator has been given for a multivariate mixture model. It has been observed that the estimator is asymptotically normally distributed with bias of size h 2 and variance of size (nh)−1.

Speed of convergence in nonparametric estimation of a multivariate μ-density and its mixed partial derivatives

Journal of Statistical Planning and Inference, 1981
Abstract Let f be a m-variate unknown density with respect to a σ-finite measure on Em, the m- dimensional Euclidean space, and let x=(x1,…,xm) and p=(p1,…,pm) be in Em, where p j≥0 are arbitrary integers. This paper exhibits kernel estimators of mixed partial derivatives f (p) (x)=(∂ p 1 +…+p m f ∂(x))/(∂x P1 1 …∂x
