Line transects of two-dimensional random fields: Estimation and design

In line-transect sampling data are collected continuously along the path travelled. These data are then used to estimate some characteristic of an entire region. We model the characteristic of the region as a linear functional of Z(), a realization of a random field, and our data as the values of Z(x) for x along the path. We study how to estimate the characteristic of interest and how to choose the path to accurately estimate it.

Design and analysis of variable fidelity experimentation applied to engine valve heat treatment process design

Summary.  When experimentation on a real system is expensive, data are often collected by using cheaper, lower fidelity surrogate systems. The paper concerns response surface methods in the context of variable fidelity experimentation. We propose the use of generalized least squares to generate the predictions. We also present perhaps the first optimal designs for variable fidelity experimentation, using an extension of the expected integrated mean-squared error criterion. Numerical tests are used to compare the performance of the method with alternatives and to investigate the robustness to incorporated assumptions. The method is applied to automotive engine valve heat treatment process design in which real world data were mixed with data from two types of computer simulation.     

正交回归多波长光度法同时测定铜、锌、钴和镍

本文应用正交回归多波长光度法,在PAN(1-(2-吡啶偶氮)-2-萘酚)-KCl显色体系中,测定铜、锌、钴和镍的混合溶液在613、578、563和539nm四个波长处的光密度,求得四种金属离子浓度与光密度间的回归方程。在该方程的适用范围内,可任意测定这四种离子的混合样品。通过方差分析表明,回归方程在α≤0.01的显著性水平上其可信度为99以上;零水平重复试验表明,方程在各金属离子浓度范围内均有良好的拟合。模拟混合物样品测定结果指出,测定误差小于3％,回收率在107.3～92.9％之间,测定浓度下限达4×10~(-7)mol·L~(-1)。四种离子可同时测定,不必分离和掩蔽。可用于合金分析和土壤分析。     

A bias analysis of Weibull models under heaped data

Retrospectively collected duration data are often reported incorrectly. An important type of such an error is heaping—respondents tend to round-off or round-up the data according to some rule of thumb. For two special cases of the Weibull model we study the behaviour of the ‘naive estimators’, which simply ignore the measurement error due to heaping, and derive closed expressions for the asymptotic bias. These results give a formal justification of empirical evidence and simulation-based findings reported in the literature. Additionally, situations where a remarkable bias has to be expected can be identified, and an exact bias correction can be performed.

Marginal Regression for Binary Longitudinal Data in Adaptive Clinical Trials

Abstract.  In an adaptive clinical trial research, it is common to use certain data-dependent design weights to assign individuals to treatments so that more study subjects are assigned to the better treatment. These design weights must also be used for consistent estimation of the treatment effects as well as the effects of the other prognostic factors. In practice, there are however situations where it may be necessary to collect binary responses repeatedly from an individual over a period of time and to obtain consistent estimates for the treatment effect as well as the effects of the other covariates in such a binary longitudinal set up. In this paper, we introduce a binary response-based longitudinal adaptive design for the allocation of individuals to a better treatment and propose a weighted generalized quasi-likelihood approach for the consistent and efficient estimation of the regression parameters including the treatment effects.
