Multivariate Analysis of Ecological Data using CANOCO Cambridge University Press Preface The multidimensional data on community composition, properties of individual populations, or properties of environment are the bread and butter of an ecologist’s life. They need to be analysed with taking their multidimensionality into account. A reductionist approach of looking at the properties of each variable separately does not work in most cases. The methods for statistical analysis of such data sets fit under the umbrella of ‘multivariate statistical methods’. In this book, we present a hopefully consistent set of approaches to answering many of the questions that an ecologist might have about the studied systems. Nevertheless, we admit that our views are biased to some extent, and we pay limited attention to other less parametric methods, such as the family of non-metric multidimensional scaling (NMDS) algorithms or the group of methods similar to the Mantel test or the ANOSIM method.We do notwant to fuel the controversy between proponents of various approaches to analysing multivariate data.We simply claim that the solutions presented are not the only ones possible, but they work for us, as well as many others. ...... 下载地址 http://www.isload.com.cn/store/yrdnsjjn4bqrx [ Last edited by cuplgz on 2008-1-6 at 09:10 ] |
