Optimal design measures under asymmetric errors, with application to binary design points
收藏 引用
JOURNAL OF STATISTICAL PLANNING AND INFERENCE 2015年 159卷 28-36页
作者: Bose, Mausumi Mukerjee, Rahul Indian Stat Inst Appl Stat Div Kolkata 700108 India Indian Inst Management Calcutta Kolkata 700104 India
We study the optimal design problem under second-order least squares estimation which is known to outperform ordinary least squares estimation when the error distribution is asymmetric. First, a general approximate th... 详细信息

JOURNAL OF STATISTICAL PLANNING AND INFERENCE 2014年 146卷 82-94页
作者: Harman, Radoslav Comenius Univ Dept Appl Math & Stat Fac Math Phys & Informat Bratislava 84248 Slovakia
Consider a linear regression experiment with uncorrelated real-valued observations and a finite design space. An approximate experimental design is stratified if it allocates given proportions of trials to selected no... 详细信息

IEEE TRANSACTIONS ON SIGNAL PROCESSING 2009年 第7期57卷 2858-2864页
作者: Wang, Wenwu Cichocki, Andrzej Chambers, Jonathon A. Univ Surrey Dept Elect Engn Ctr Vis Speech & Signal Proc Guildford GU2 7XH Surrey England RIKEN Brain Sci Inst Lab Adv Brain Signal Proc Wako Saitama 3510198 Japan Univ Loughborough Adv Signal Proc Grp Dept Elect & Elect Engn Loughborough LE11 3TU Leics England
Using the convolutive nonnegative matrix factorization (NMF) model due to Smaragdis, we develop a novel algorithm for matrix decomposition based on the squared Euclidean distance criterion. The algorithm features new ... 详细信息

COMPUTATIONAL STATISTICS & DATA ANALYSIS 2010年 第6期54卷 1419-1425页
作者: Yu, Yaming Univ Calif Irvine Dept Stat Irvine CA 92697 USA
We study a class of multiplicative algorithms introduced by Silvey et al. (1978) for computing D-optimal designs. Strict monotonicity is established for a variant considered by Titterington (1978). A formula for the r... 详细信息

MATHEMATICA SLOVACA 2009年 第6期59卷 693-704页
作者: Harman, Radoslav Trnovska, Maria Comenius Univ Fac Math Phys & Informat Dept Appl Math & Stat SK-84248 Bratislava Slovakia
In the paper we solve the problem of D (a"<)-optimal design on a discrete experimental domain, which is formally equivalent to maximizing determinant on the convex hull of a finite set of positive semidefinite... 详细信息
