Nonparametric Estimates of Low Bias

open access: yesRevstat Statistical Journal, 2012
We consider the problem of estimating an arbitrary smooth functional of k ≥ 1 distribution functions (d.f.s) in terms of random samples from them. The natural estimate replaces the d.f.s by their empirical d.f.s. Its bias is generally ∼ n−1 , where n is

Multivariate Unimodality

open access: yesThe Annals of Statistics, 1976
For univariate distributions there is a generally accepted definition of unimodality due to Khintchine which requires the existence of a number $a$, called vertex, such that the distribution function is convex on $(-\infty, a)$ and concave on $(a, \infty)$.

Multivariate Goppa Codes

open access: yesIEEE Transactions on Information Theory, 2023
In this paper, we introduce multivariate Goppa codes, which contain as a special case the well-known, classical Goppa codes. We provide a parity check matrix for a multivariate Goppa code in terms of a tensor product of generalized Reed-Solomon codes. We prove that multivariate Goppa codes are subfield subcodes of augmented Cartesian codes.

Multivariate SPC for total inertial tolerancing

open access: yesInternational Journal of Metrology and Quality Engineering, 2013
This paper presents a joint use of the T2 chart and total inertial tolerancing for process control. Here, we will show an application of these approaches in the case of the machining of mechanical workpieces using a cutting tool. When
