PRIMER-e v7 生態學多變數統計軟體

Thousands of researchers globally trust PRIMER for ingenuity and clarity in multivariate analysis.

Analyse ecological data, or any other data, that would benefit from a safe non-parametric approach​.
PRIMER v7 provides a wide range of univariate, graphical and multivariate routines for analysing arrays of species-by-samples data from community ecology.​

Data are typically of abundance, biomass, % area (or line) cover, presence/absence etc. and arise in biological monitoring of environmental impacts and more​ fundamental ecological studies. Also catered for are matrices of physical values and chemical concentrations, which are analysed in their own right or in​ parallel with biological assemblage data, e.g., to examine co-variation of biotic changes with physico-chemical conditions.​

Though the analysis requirements for biological assemblage data are a principle focus, the package is equally applicable (and increasingly being applied)​ to other data structures which are multivariate or can be treated as such.​

The unifying feature is that all datasets can be reduced to an appropriate triangular matrix representing the resemblance of every pair of samples in terms of​ their assemblages, suites of biomarkers, particle size distributions, shape of growth curves, etc. Clustering and ordination techniques are then able to​ display the relationships among samples, and permutation tests are used to test hypotheses.​

Easy manipulation of data and results
The PRIMER Workspace (*.pwk)

• Work on multiple data-sets, graphics and output files
   simultane ously within a single interactive & intuitive
   graphical Windows environment.​
• Keep track of all your work easily using the tree-like
   navigation pane.​
• Input/output data from Excel, .csv, .txt or 3-column
• View and change the colours, fonts, look & feel of
   your plots and graphics on-screen.​
• Copy/print/export results to .jpg, .emf, .tif, .gif, .png,
  .bmp or .rtf files.
• Power and flexibility in specifying analyses.
• Identify important subsets of samples or variables.​
• Define group structures for tests and displays.​
• Handle relatively large data sets (subject only to
  available Windows memory).​
• Merge or split data on specified criteria.​
• Unleash the time-saving power of in-built Wizards
  for matrix displays and core analyses.

Ordination techniques for visualising data, including principal
components analysis (PCA), plus non-metric, metric or threshold
-metric multi-dimensional scaling (nMDS, mMDS, tmMDS).​
Visualise high-dimensional data in 2d or 3d. Customise text,
colours and symbols. Add essential information with overlays,
such as clusters, trajectories, bubbles, images, vectors, or minimum spanning trees.​
Use bootstrapping to show confidence regions on MDS plots.
Spin, expand, rotate, animate, save and share your insightful

Perform hierarchical clustering into sample (or variable/species) groups, with single, complete, group-average or flexible-beta
linkage options.​
Create cophenetic distance matrices and plot dendrograms.
Customise, rotate, collapse, zoom in, or print them out over
multiple pages to capture all of the finer details.​
Similarity profiles (SIMPROF) and associated permutation tests
identify the coherence of groups of samples or species.​
Divisive clustering methods can be unconstrained (UNCTREE),
or constrained by environmental (or other) variables (LINKTREE), while krCLUSTER does a non-parametric version of k-means

Shade plots and Heat maps​ 
Display actual values in 2d or 3d with grey-scale or colour
spectra of choice.​
Salient patterns are uncovered with ease.​
Samples and variables can be sorted according to various
criteria, including gradients, clustering constraints, or groupings.​
Labels and symbols are easily modified and customised

Non-parametric tests​ 
Permutation-based hypothesis testing using analysis of
similarities (ANOSIM), which tests for differences between
groups of multivariate samples from different times, locations,
experimental treatments, etc. PRIMER’s algorithms now support most three-way designs for these fully non-parametric tests.​
Identify species primarily providing discrimination between two
groups of samples (SIMPER).​
Test for seriation and other Mantel-type tests for sequential data in time or space.​
Relate matrices to one another or identify subsets of variables
which together produce a ‘BEST’ Mantel-type match to a given
resemblance matrix. ​
Permutation tests include variable-selection steps to ensure
rigorous statistical inference.​

Biodiversity analyses​ 
Use taxonomic, functional and/or phylogenetic information to
inform biodiversity assessments. Test against master lists using
sub-sampling algorithms.​
Calculate a multitude of classic and novel diversity indices or
summary statistics of individual variables, with aggregation
tools for analysing data at higher taxonomic levels.​
Access a wide choice of flexible plotting functions for individual
variables: line, histogram, scatter, bar, box, means, surface or
Draftsman plots.​
Ecology-specific tools are at your fingertips, such as dominance
plots, geometric class plots, or abundance biomass curves (ABC).​

Extensive manuals and examples​ 
PRIMER version 7 includes context-specific Help buttons, as well as extensive downloadable manuals in searchable pdf format:​
“Change in Marine Communities (3rd ed.)”, explaining all of the
statistical methods underlying the software in non-mathematical terms; and​
“PRIMER v7: User Manual / Tutorial”, explaining precisely how to
implement the methods and all software utilities.​
A large number of full genuine data sets are included with the
package so that the user can replicate analyses given in the
manual and authored scientific publications.​

will not run natively on Apple Mac OSX, but it is possible to use
it via virtualization software or Boot Camp.
