When comparing alternate product formulations, or evaluating competitors' formulations, researchers often conduct blind, forced choice product tests. In this study, the authors present an approach to designing these tests and evaluating their results. Two types of tests are considered: repeat...

<p><span style="font-size: 11.000000pt; font-family: 'CMR10';">In the paper we study the impact of incomplete information to precision of results of stochastic optimization. It is assumed that the stochastic characteristics of optimized system are evaluated from the data. However, the observations can be incom- plete, namely, we consider the random...</span></p>

Life cycle approaches are critical for identifying and reducing environmental burdens of products. While these methods can indicate potential environmental impacts of a product, current Life Cycle Assessment (LCA) methods fail to integrate the multiple impacts of a system into unified measures...

Some extensions of entropy and KL information to the survival function have been recently proposed. We first compare some extensions of KL information and provide a criterion in choosing one among those extensions. Then we study moment constraints for maximum cumulative residual entropy...

The Fisher information on θ of the r-size weighted pdf fr(x;θ) and its parent pdf f(x;θ) are compared leading to some characterization properties for f(x;θ). Additionally, some bounds for the Fisher information in terms of r are also presented.

Computer simulations are often used to replace physical experiments for exploring the complex relationships between input and output variables. We study the optimal design problem for the prediction of a stationary Ornstein–Uhlenbeck sheet on a monotonic set with respect to the integrated mean...

An important property of Fisher information is that it decreases weakly under transformation of random variables. Kagan and Rao (2003) [A. Kagan, C.R. Rao, Some properties and applications of the efficient Fisher score, J. Statist. Plann. Inference 116 (2003) 343–352] showed that, in the...
