Analysis of similarities (ANOSIM) for 3‐way designs Open
Analysis of similarities ( ANOSIM ) is a robust non‐parametric hypothesis‐testing framework for differences in resemblances among groups of samples. To date, the generalisation and use of ANOSIM to analyse various 2‐way nested and crossed …

Analysis of similarities (ANOSIM) for 2‐way layouts using a generalised ANOSIM statistic, with comparative notes on Permutational Multivariate Analysis of Variance (PERMANOVA) Open
ANOSIM (Analysis of Similarities) is a robust non‐parametric hypothesis testing framework for differences in resemblances among groups of samples. The generalised ANOSIM statistic R O is defined as the slope of the linear regression of ran…

A generalised analysis of similarities (ANOSIM) statistic for designs with ordered factors Open
In the study of multivariate data, for example of change in ecological communities, ANOSIM is a robust non‐parametric hypothesis‐testing framework for differences in resemblances among groups of samples. RELATE is a non‐parametric Mantel t…

Some solutions to the multivariate Behrens–Fisher problem for dissimilarity‐based analyses Open
Summary The essence of the generalised multivariate Behrens–Fisher problem (BFP) is how to test the null hypothesis of equality of mean vectors for two or more populations when their dispersion matrices differ. Solutions to the BFP usually…
