Control charts are used to identify the presence of assignable cause of variation in the process. Non-parametric control chart is an emerging area of recent development in the theory of SPC. Its main advantage is that it does not require any knowledge about the underlying distribution of the variable. In this paper a non-parametric control chart for controlling variability has been developed. I...

Author Contact: David Giles, Dept. of Economics, University of Victoria, P.O. Box 1700, STN CSC, Victoria, B.C., Canada V8W 2Y2; e-mail: [email protected]; FAX: (250) 721-6214 Abstract Using data relating to ‘number one’ hits on the Billboard Hot 100 chart, we find clear evidence of increasing returns to information in the U.S. market for popular music. This evidence supports related findings for ...

We use Inductive Logic Programming (ILP) within a chart-parsing framework for grammar learning. Given an existing grammar G, together with some sentences which G can not parse, we use ILP to nd the \miss-ing" grammar rules or lexical items. Our aim is to exploit the inductive capabilities of chart parsing, i.e. the ability to eeciently determine what is needed for a parse. For each unparsable s...

Scott (eds.), The Little Black Book of Neuropsychology: A Syndrome-Based Approach, DOI 10.1007/978-0-387-76978-3_2, © Springer Science+Business Media, LLC 2011 Abstract This chapter provides an overview of the medical chart, and its sections. The neuropsychologist will be provided with detailed information about how to decipher some of the many abbreviations, and we als...

Mukherjee and Chakraborti 1 proposed a single distribution-free (nonparametric) Shewhart-type chart based on the Lepage 2 statistic for simultaneously monitoring both the location and the scale parameters of a continuous distribution when both of these parameters are unknown. In the present work, we consider a single distribution-free CUSUM chart, based on the Lepage 2 statistic, referred to as...

Oliver Hinz, Jochen Eckert The Impact of Search and Recommendation Systems on Sales in Electronic Commerce The Internet and related technologies have vastly expanded the variety of products that can be profitably promoted and sold by online retailers. Furthermore, search and recommendation tools reduce consumers’ search costs in the Internet and enable them to extend their search from a few eas...

Climate research produces a wealth of multivariate data. These data often have a geospatial reference and so it is of interest to show them within their geospatial context. One can consider this configuration as a multifield visualization problem, where the geo-space provides the expanse of the field. However, there is a limit on the amount of multivariate information that can be fit within a c...
