Approximate D-optimal designs of experiments on the convex hull of a finite set of information matrices
收藏 引用
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

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

Quasi-Newton algorithm for optimal approximate linear regression design: Optimization in matrix
收藏 引用
JOURNAL OF STATISTICAL PLANNING AND INFERENCE 2019年 198卷 62-78页
作者: Gaffke, N. Schwabe, R. Univ Magdeburg Fac Math PF 4120 D-39016 Magdeburg Germany
Given a linear regression model and an experimental region for the independent variable, the problem of finding an optimal approximate design calls for minimizing a convex optimality criterion over a convex set of inf... 详细信息

algorithmic and analytical construction of efficient designs in small blocks for comparing consecutive pairs of treatments
收藏 引用
JOURNAL OF STATISTICAL COMPUTATION AND SIMULATION 2017年 第16期87卷 3195-3207页
作者: Huda, S. Mukerjee, Rahul Kuwait Univ Dept Stat & OR Fac Sci POB 5969 Safat 13060 Kuwait Indian Inst Management Calcutta Kolkata India
Optimal block designs in small blocks are explored under the A-, E- and D-criteria when the treatments have a natural ordering and interest lies in comparing consecutive pairs of treatments. We first formulate the pro... 详细信息

An efficient algorithm for Elastic I-optimal design of generalized linear models
收藏 引用
CANADIAN JOURNAL OF STATISTICS-REVUE CANADIENNE DE STATISTIQUE 2021年 第2期49卷 438-470页
作者: Li, Yiou Deng, Xinwei Depaul Univ Dept Math Sci Chicago IL 60604 USA Virginia Tech Dept Stat Blacksburg VA 24061 USA
The generalized linear models (GLMs) are widely used in statistical analysis and the related design issues are undoubtedly challenging. The state-of-the-art works mostly apply to design criteria on the estimates of re... 详细信息

Optimal designs with string property under asymmetric errors and SLS estimation
收藏 引用
STATISTICAL PAPERS 2018年 第3期59卷 1255-1268页
作者: Huda, S. Mukerjee, Rahul Kuwait Univ Fac Sci Dept Stat & OR POB 5969 Safat 13060 Kuwait Indian Inst Management Calcutta Joka Diamond Harbour Rd Kolkata 700104 India
We consider the optimal design problem when the design space consists of binary vectors with a string property, i.e., a single stretch of ones. This is done in the framework of second-order least squares estimation wh... 详细信息

MONOTONIC CONVERGENCE OF A GENERAL algorithm FOR COMPUTING OPTIMAL DESIGNS
收藏 引用
ANNALS OF STATISTICS 2010年 第3期38卷 1593-1606页
作者: Yu, Yaming Univ Calif Irvine Dept Stat Irvine CA 92697 USA
Monotonic convergence is established for a general class of multiplicative algorithms introduced by Silvey, Titterington and Torsney [Comm. Statist. Theory Methods 14 (1978) 1379-1389] or computing optimal designs. A ... 详细信息

Efficient algorithms for constructing D- and I-optimal exact designs for linear and non-linear models in mixture experiments
收藏 引用
SORT-STATISTICS AND OPERATIONS RESEARCH TRANSACTIONS 2019年 第1期43卷 163-189页
作者: Martin Martin, Raul Garcia-Camacha Gutierrez, Irene Torsney, Bernard Univ Castilla La Mancha Dept Math Ciudad Real Spain Univ Glasgow Sch Math & Stat Glasgow Lanark Scotland
The problem of finding optimal exact designs is more challenging than that of approximate optimal designs. In the present paper, we develop two efficient algorithms to numerically construct exact designs for mixture e... 详细信息

A new monotonic algorithm for the E-optimal experiment design problem
收藏 引用
STATISTICS & PROBABILITY LETTERS 2021年 174卷 109097-109097页
作者: Sahu, Nitesh Babu, Prabhu Indian Inst Technol Delhi Ctr Appl Res Elect New Delhi 110016 India
In this paper, we develop a new monotonic algorithm for the E-optimal design problem, for which no simple monotonic algorithm is known to exist, using the idea of majorization-minimization. The available algorithms in... 详细信息
