[EAN: 9780973620924], Neubuch, [PU: Razorbill Press], KIM N. I. BELL,BIOSTATISTICS,ECOLOGY,REFERENCE,BIOLOGY, Paperback. 184 pages. Dimensions: 9.7in. x 7.4in. x 0.6in.This book makes periodic regression readily accessible. It provides worked-out examples, and text that describes why each step is taken (and what steps to not take). Periodic regression is suited to situations where a Y variable is measured over (around) a cycle, e. g. air temperature over the course of a day, or year; this is sometimes called the cylindrical situation---think of a 24h clock, lying flat, and temperatures marked on bars at times around its circumference. The uses or periodic regression are not restricted to only those situations where one had a direct interest in the cycles. Even if the interest is the effect of A and B on Y, if a third variableCalso affectsY thenany analysis obtains improved accuracy for Aand BwhenCis included. Likewise, cycles can affect many measures, so their inclusion improves the analysis for the effects of the variables of main interest. This would apply to many examples of ecological, biological, and medical research. Written in a welcoming style, written to be accessible --- for instance Sec. 11. 1. 2 The very basics (stats in the wild west) --- the book anticipates readers ranging from apprehensive to advanced. Most tricky concepts are explained more than one way. It is copiously illustrated with conceptual diagrams and worked-out examples. If you are an advanced reader you may wish to go straight to Ch. 6, the chapter on periodic regression itself, referring to the cross-referenced sections as needed. Resource chapters provide the basic geometry, key tools for circular stats, the handling of dates and natural cycles, and a simple notation system to make formulas and calculations more readable. There is an index, a glossary, and a Day-of-Year table. Some special tools and topics are addressed. Sec. 6. 4. 5 shows how to calculate the joint significance of one or more variables in a regression; this is needed because each cycle will always be expressed by two variables. Sec. 6. 4. 6 addresses some cautions and uses simulation to illuminate the issue of non-orthogonality in data with uneven spacing or missing or replicated values, as is liable to happen in field work or any system where logistics interfere with the plan; the simulations show that the effect on inference is, at least, surprisingly small. Sec. 10. 2. 1. provides the text for some core macros that can simplify and add reliability to data conversion and calculation (e. g. ) of the phase angle implied by any pair of sine and cosine. And if you think sines and cosines are material for headaches, Figure 3-1 is better than an aspirin. Even where the topics are somewhat advanced, the book attempts to maintain accessibility. It is written to help peopleenjoy statistics, anduse and judge them well. This item ships from multiple locations. Your book may arrive from Roseburg,OR, La Vergne,TN.

ID: 11220082917

[EAN: 9780973620924], Neubuch, [PU: Razorbill Press, Canada], Language: English . Brand New Book ***** Print on Demand *****. TITLE: ANALYSING CYCLES-in biology medicine. A practical introduction to circular variables and periodic regression. With stats refresher. MOTIVATION: Cycles surround us. Indeed, they are the essence of life, and critically important in biology and medicine. We need to know how to analyse and understand them. But, too often, researchers are given poor advice: to keep cycles out of data-by restricting sampling to the same time of day, tide, etc. That s a bad approach; it s costly because you have to wait for your chosen special times, and even more costly with multiple cycles because you have to wait for even rarer conjunctions of special times (e.g. 1100h and high tide) in each of them. The final consequence is: no matter how carefully you worked, the opportunity to describe key cycles is lost, so your findings are virtually meaningless because they can t be generalised outside the special times you chose. In fact, it is easier, more useful, and far more beautiful, to put cycles into the analysis than to keep them out of the data. This book shows you how. ABOUT THE BOOK: Written in a welcoming style, the book anticipates readers ranging from apprehensive to advanced. It is copiously illustrated with conceptual diagrams and worked-out examples. It contains all that s needed to get started: even the basic trigonometry and a crisp stats refresher. All you need is the book, your data, and Excel or a stats package. ABOUT THE AUTHOR: Dr. Bell has his degrees (BSc., MSc., PhD.) from Memorial University of Newfoundland and Dalhousie University in Halifax. He has given courses and seminars in biology, introductory statistics, data management, and science ethics at Memorial University and Rhodes University. His core interests are in aquatic ecology: anadromous gobies, recruitment processes, early life histories, and conservation. He is a strong voice in the role of science in the policy and implementation of fishery management, and a strong proponent of science ethics particularly in government decision-making. He has consistently pointed out the problems that result from secrecy, as argued by the venerable C.P. Snow in Science and Government. He has reviewed for many journals, reported to the House of Commons, and, for COSEWIC (Committee on the Status of Endangered Wildlife in Canada), authored the 1998 Status Report on Atlantic Cod in Canada. That Report resulted in Canada s first at-risk designation of a commercial marine fish. But that is another story. The author s interest in circular statistics began with periodic data for which analysis advice was lacking, and he hopes to correct the situation wherein biology is dominated by cycles that are generally ignored, at potentially great cost, because of a lack of knowledge of the proper techniques.
