Fathom Toolbox for Matlab

Distribution-free methods for multivariate analysis of ecological or environmental data.

Highlights of the Toolbox's capabilities include support for:

- Dissimilarity Profile Analysis (= Similarity Profile Analysis, SIMPROF)
- Canonical Analysis of Principal Coordinates (CAP)
- Nonparametric MANOVA (NP-MANOVA, perManova )
- Nonparametric Homogeneity of Multivariate Dispersion (NP-DISP)
- Redundancy Analysis (RDA)
- Distance-based RDA (db-RDA)
- Canonical Discriminant Analysis (CDA)
- Principal Coordinates Analysis (PCoA)
- Canonical Correlation Analysis (CCorA)
- Nonlinear CAP (NCAP)
- Principal Coordinates of Neighbor Matrices (PCNM)
- Moran's Eigenvector Maps (MEM)
- Multivariate Mantel Correlograms
- Analysis of Similarity (ANOSIM)
- Similarity Percentages Analysis (SIMPER)
- Best Subsets Analysis (BIOENV, BEST)
- Maximum Likelihood Estimation (MLE)
- Random Forests (RF)
- Bootstrap Resampling & Randomization Tests
- Mantel Tests
- Procrustes Analysis
- Minimum Spanning Trees (MST)
- Principal Components Analysis (PCA)
- Multiple Regression
- Permutation-based Analysis of Covariance (ANCOVA)
- von Bertalanffy Growth Modelling
- AIC or BIC based stepwise variable selection in RDA and db-RDA
- Species Indicator Values (IndVal)
- Oceanographic tools (progressive vector diagrams, vector plots, etc.)

- over 50 measures of distance and dissimilarity
