![]() (2002) Monitoring Ecological Impacts: Concepts and Practice in Flowing Waters. Pierre Legendre’s web page: If you are interested in environmental monitoring, you might also want to check out this book:ĭownes B.J., Barmuta L.A., Fairweather P.G., Faith D.P.,Keough M.J.,Lake P.S., Mapstone B.D.Much of this has been subsumed by the combination of Primer and Permanova (see ). Marti Anderson’s web page: some of her older software.Pierre Legendre’s page largely supports his Numerical Ecology book, but also has lots of other useful software. Marti’s site includes distance-based redundancy analysis (Chapter 17) and her robust, non-parametric MANOVA approach (Chapter 18). Two of the best places for new, interesting multivariate approaches are web sites of Marti Anderson and Pierre Legendre. Documentation for R (R project for statistical computing). This is the enhanced distribution of R from Microsoft. Performs regression analysis to estimate values of parameters. You can also download the GPower manual if you want a copy of it. Statistical and mathematical software that handles all your statistical needs. There is a version available for Windows and Mac operating systems. Designed by researchers to help you analyze scientific and business data. The program can be cited as: Walsh, C., and Mac Nally, R. It is a general statistical package useful in teaching statistical ideas. Chris Walsh and Ralph Mac Nally from Monash University have written a program in the R language for doing hierarchical partitioning. There are very few tools that can help you calculate the power of an analysis, and. 141-142), we describe hierarchical partitioning, a procedure for decomposing the variability contributed by each predictor variable in a multiple linear regression model. I love that it is mac-friendly and can calculate power for different tests. ![]() Russ Lenth’s web-based Power analysis using java applets at Hierarchical partitioning.Can do a priori, post hoc, compromise, criterion, or sensitivity power analyses. Why use GPower Simple, clean interface is easy to learn and easy to use - great teaching tool. It is available for both Windows and Mac. This add-in allows you to program pretty much any power analysis into excel. GPower is a free, open source program for power analysis and sample size calculations. He has also created a small add-in for Microsoft Excel, PiFace, which includes the non-central probability distribution functions need to compute power. Lenth has developed software for several years, beginning with PowerPack, through to his current Java applets that allow you to do power analysis on line. Both are free, but you should acknowledge the use software in papers. We have provided links to two pieces of software that we find useful for power analyses, GPower, and the software provided by Russ Lenth, of the Univesity of Iowa. ![]()
