Numerical Taxonomy System, Version 2.2 for Windows XP, Vista, & Win7 including 64 bit
|Similarity and dissimilarity: correlation, distance, 34 association coefficients, and 11 genetic distance coefficients.|
|Clustering: UPGMA and other hierarchical SAHN methods (allows for ties). Neighbor-joining method (including the new unweighted version). Several types of consensus trees.|
|Graph theoretic methods: minimum-length spanning trees. Graphs (unrooted trees) from the neighbor-joining method.|
|Ordination: principal components & principal coordinates analysis, correspondence analysis, metric & non-metric multidimensional scaling analysis, singular-value decompositions, projections onto axes and Burnaby's method. Canonical variates analysis. Programs for multiple factor analysis, common principal components analysis, partial least-squares, multiple correlation, and canonical correlations are also included.|
|Interactive graphics: phenograms, phylogenetic trees, 2D scatter plots , comparison of dis/similarity matrices, Fourier plots of outlines, Procrustes plots, and 3-D perspective plots.|
|Multivariate tests: canonical variates analysis, tests for homogeneity of covariance matrices, tests for number of dimensions, generalized multivariate multiple regression analysis. There are also provisions for bootstrap, jackknife, and simulation experiments.|
|Geometric morphometrics: includes specialized modules for Procrustes analysis to superimpose landmark configurations, plotting the results of a Procrustes analysis, Fourier analysis (including 2D and 3D elliptic) of outline shapes, plotting outlines and Fourier coefficients, and computation of 2D and 3D partial warp scores and estimates of the uniform component.|
|Other: includes comparison of matrices by cophenetic correlation, Mantel test, 3-way Mantel test, data standardization, and matrix transformations (simple functions, deletion, and now matrix transpose). Matrices can be split or combined.|
Licensed users can download a copy of the latest update to NTSYSpc when an update becomes available (usually several times a year as new features added or bugs fixed). Users should check our Frequently Asked Questions page for helpful hints on the use of NTSYSpc and links to a Getting Started Guide and an Installation Guide.
Requirements: Windows XP/Vista/Win7/Win8/Win 8.1 including 32 and 64 bit versions. Software conforms to Windows standards so it should work well using Windows emulators and virtual machines including on a Mac. It should also work well on future versions of Windows. Requires about 5 MB of disk space after installation is complete.
Cost: $350 ($250 for educational and governmental institutions). Upgrade from previous version (2.0 or 2.1): $195 ($150 educational and governmental institutions). 10-user site licenses are $900 ($700 educational and governmental institutions). There are reduced rates for larger numbers of users, e.g., $1,350 for a 20 user license ($1025 for educational and governmental institutions). There are also shipping costs dependent on location (free if download only is selected). Note our Return policy.
