...A Statistical Perspective on Data Mining Ranjan Maitra∗ Abstract Technological advances have led to new and automated data collection methods. Datasets once at a premium are often plentiful nowadays and sometimes indeed massive. A new breed of challenges are thus presented – primary among them is the need for methodology to analyze such masses of data with a view to understanding complex phenomena and relationships. Such capability is provided by data mining which combines core statistical techniques with those from machine intelligence. This article reviews the current state of the discipline from a statistician’s perspective, illustrates issues with real-life examples, discusses the connections with statistics, the differences, the failings and the challenges ahead. 1 Introduction The information age has been matched by an explosion of data. This surfeit has been a result of modern, improved and, in many cases, automated methods for both data collection and storage. For instance, many stores tag their items with a product-specific bar code, which is scanned in when the corresponding item is bought. This automatically creates a gigantic repository of information on products and product combinations sold. Similar databases are also created by automated book-keeping, digital communication tools or by remote sensing satellites, and aided by the availability of affordable and effective storage mechanisms – magnetic tapes, data warehouses and so on. This has created a situation...

...data analysis capabilities that can assist the management in decision making. Business Analytics is a set of techniques and processes that can be used to analyse data to improve business performance through fact-based decision making. Business Analytics is the subset of Business intelligence, which creates capabilities for companies to compete in the market effectively. Business Analytics is likely to become one of the main functional areas in most companies. Analytics companies develop the ability to support their decisions through analytic reasoning using a variety of statistical and mathematical techniques. thomas devonport in his book titled, “competing on analytics: the new science of winning”, claims that a significant proportion of high-performance companies have high analytical skills among their personnel. On the other hand, a recent study has also revealed that more than 59% of the organizations do not have information required for decision-making. in a recent article1 based on a survey of nearly 3000 executives, Mit sloan Management Review reported that there is striking...

...Energy Policy 31 (2003) 721–734 Electricity and externalities in South Africa Randall Spalding-Fechera,*, David Khorommbi Matibeb b a Energy and Development Research Centre, University of Cape Town, Private Bag, Rondebosch 7700, South Africa Gauteng Department of Agricultural Conservation and Environment, PO Box 8769, Johannesburg 2000, South Africa Abstract As the electricity supply sector in developing countries undergoes increasingly rapid restructuring, and technology and fuel choices widen, understanding the environmental implications of investment choices becomes ever more important. The objective of this paper is to expand previous analysis of the external costs of electric power generation in South Africa. We present a quantitative analysis of air pollution impacts on human health, damages from greenhouse gas emissions, and the avoided health costs from electrification, as well as discussing other impacts qualitatively. The central estimate of total external costs is R7.3 billion, or 4.4 cents per unit of coal-fired power generated. Relative to current electricity prices, the external costs are approximately 40 and 20 per cent of industrial and residential tariffs, respectively. We then discuss policy options for addressing these costs, including taxation, tradable permit systems, and integrated resource planning, as well as expanded regional energy trade and the possibility of accessing climate change-related funding for cleaner electricity production. r 2002 Elsevier...
