CAP

Community Analysis Package

Suitable for undergraduate and post graduate students and researchers in biological

and geological sciences, CAP is a general multivariate analysis package for Windows

PCs, with superb graphics. It is easy to use and affordable. It offers all the analytical

techniques commonly used by community ecologists, and researchers in other fields

such as palaeontology, archaeology and the social sciences. It is particularly useful for

ecological teaching because it allows students to quickly enter data, try different

transformations, and explore a wide range of methods within a familiar Windows

setting.

Its principal methods are:

Non metric Multidimensional Scaling (NMDS)

Detrended Correspondence Analysis (DECORANA)

Two way INdiscator Species Analysis (TWINSPAN)

Analysis of Similarity (ANOSIM) and Similarity Percent (SIMPER)

Agglomerative clustering

Species Filtering

Reciprocal Averaging

Principal Components Analysis (PCA)

26 Similarity and distance measures

Divisive cluster analysis

Association analysis

CAP also feature  Help Assist  an (optional) always on help panel to guide you through

your analysis, to tell you what s appropriate and what the pitfalls of any technique are

likely to be.

With superb graphical output that gives you complete control over how you want your

graphics to look, CAP is an indispensible part of every ecologist s analytical toolbox.

ECOM

ECOM

 is a Windows  program with a range of analytical techniques to detect,

visualise and order relationships in multivariate data where the researcher has

information on both the species present and the most influential environmental

variables.

The principal methods are:
