Comparison of gene expression for two groups of individuals form an important subclass of microarray experiments. We study multivariate procedures, in particular use of Hotelling's T2 for discrimination between the groups with a special emphasis on methods based on few genes only. We apply the methods to data from an experiment with a group of atopic dermatitis patients compared with a control ...

It has been long recognized that an exhaustible-resource monopsonist faces a commitment problem similar to that of a durable-good monopolist. Indeed, Hörner and Kamien (2004) demonstrate that the two problems are formally equivalent under full commitment. We show that there is no such equivalence in the absence of commitment. The existence of a choke price at which the monopsonist adopts the su...

Adaptive sample size and sampling intervals schemes have been widely used to improve the statistical efficiency of Hotelling T control chart in detecting small changes when the quality of a product or a process can be characterised by the multivariate distribution of quality characteristics. In this paper, we design a Hotelling T scheme varying sample sizes and sampling intervals (VSSI-T) for a...

For high-dimensional small sample size data, Hotelling's T2 test is not applicable for testing mean vectors due to the singularity problem in covariance matrix. To overcome problem, there are three main approaches literature. Note, however, that each of existing may have serious limitations and only works well certain situations. Inspired by this, we propose a pairwise Hotelling method vectors,...

I develop a simple Hotelling model which corresponds the distribution of consumer preferences to the intensity of competition. This is a new perspective on consumer distribution in the Hotelling model. I impose two properties, mean preserving spread (MPS) and monotone likelihood ratio property (MLRP), on distribution functions. These properties provide a way to measure the intensity of competit...

Recent advances in model observers that predict human perceptual performance now make it possible to optimize medical imaging systems for human task performance. We illustrate the procedure by considering the design of a lens for use in an optically coupled digital mammography system. The channelized Hotelling observer is used to model human performance, and the channels chosen are differences ...
