Mixed Effects Models and Extensions in Ecology with R (2009). Zuur, Ieno, Walker, Saveliev and Smith. Springer

Building on the successful Analyzing Ecological Data (2007) by Zuur, Ieno and Smith, the authors now provide an expanded introduction to using regression and its extensions in analyzing ecological data. As with the earlier book, real data sets from postgraduate ecological studies or research projects are used throughout. The first part of the book is a largely non-mathematical introduction to linear mixed effects modeling, GLM and GAM, zero inflated models, GEE, GLMM and GAMM. The second part provides ten case studies that range from koalas to deep sea research. These chapters provide an invaluable insight into analyzing complex ecological datasets, including comparisons of different approaches to the same problem. By matching ecological questions and data structure to a case study, these chapters provide an excellent starting point to analyzing your own data. Data and R code from all chapters are available. Order from Springer or Amazon.com

Book reviews

• Basic and Applied Ecology (2009). Bernd Gruber: ....... This multitude of examples makes this book unique in the statistical literature on mixed models and many readers will find a suitable example that serves as a blue-print for analyzing their own data.........I highly recommend the book to anyone who is familiar with basic statistics such as t-tests, analysis of variance and who wants to expand his/her statistical knowledge to analyze ecological data.
• A very nice review in the Journal of Statistical Software from Aaron Christ.

Errata

A word document with corrections is available. We also updated the GAM code for recent R versions.

Data and R code

The data files are supplied as an R package; download it, start R, click on Packages, and select "Install from local zip file". If you do not use R, you can obtain the data in ascii format. All R code is provided in a zip file. 

UPDATE 24 August 2009: The R code for the GAM sections have been updated. It now runs on R 2.9.1.

Mac and LINUX users

Our package was written on computers using the operating systems Microsoft VISTA & XP. You need to do a little bit of extra work to get it running under Mac and LINUX computers. Here is a pdf from Prof. Andy Hector describing what to do. In case of problems, please consult the R newsgroup (sorry, we don't have a Mac, so can't help you any further). Note that you should be able to open our Tinn-R files with an ascii editor.    

Amazon

At times, the book is selling quite well on Amazon.co.uk.  

 

 Comments from readers

• ... I have been using your book Mixed Effects Models and Extensions in Ecology with R. I would just like to tell you that it has been extremely useful and easy to understand for me as a non-statistician, and provided excellent guidelines! I will most definitely be using it many more times! Thank you very much! Regards, Michelle Greve. Aarhus University. Aarhus. Denmark
