WHAT IS OPERATIONS RESEARCH? A common misconception held by many is that O.R. is a collection of mathematical tools.  While it is true that it uses a variety of mathematical techniques, operations research has a much broader scope.  It is in fact a systematic approach to solving problems, which uses one or more analytical tools in the process of analysis.  Perhaps the single biggest problem with O.R. is its...

The Joys of Paradise Those who enter Paradise will do so in their most perfect, beautiful form.  Their hearts will be one.  They will neither spit, nor blow their noses, or defecate.  They will remain young forever, strong and potent without the inconveniences of body hair. The worldly pleasures pretty much fade in the face of heavenly delights.  The pleasures of this world are fleeting and short-lived,...

Evidence of the early human occupation of Algeria is demonstrated by the discovery of 1.8 million year old Oldowan stone tools found at Ain Hanech in 1992. In 1954 fossilised Homo erectus bones were discovered by C. Arambourg at Ternefine that are 700,000 years old. Neolithic civilization (marked by animal domestication and subsistence agriculture) developed in the Saharan and...

Software In the late '70's the Centre de Geostatistique, Fountainebleau, began a master level program in geostatistics (two years) which attracted a steady stream of students from industry and goverment in various countries. In cooperation with Shell Oil and the Bureau de Recherche Geologie Mathematique (the French USGS), a commercial software package called BLUEPACK was developed. The early version was only ported to the...

The Nature of Data and Variation Although natural phenomena in the real life are unpredictable, the designs of experiments are bounded to generate data that varies because of intrinsic (internal to the system) or extrinsic (due to the ambient environment) effects. How many natural processes or phenomena in the real life that have an exact mathematical closed-form description and are completely deterministic can we describe?...

Final stage of the initial data analysis During the final stage, the findings of the initial data analysis are documented, and necessary, preferable, and possible corrective actions are taken. Also, the original plan for the main data analyses can and should be specified in more detail and/or rewritten. In order to do this, several decisions about the main data analyses can and should be made: In the case of non-normals:...

Almost all educational programmes in biostatistics are at postgraduate level. They are most often found in schools of public health, affiliated with schools of medicine, forestry, or agriculture, or as a focus of application in departments of statistics. In the United States, where several universities have dedicated biostatistics departments, many other top-tier universities integrate biostatistics faculty into...

A field of applied statistics, survey methodology studies the sampling of individual units from a population and the associated survey data collection techniques, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys. Statistical surveys are undertaken with a view towards making statistical inferences about...
