MVSP is an inexpensive and easy
to use program that performs a number of multivariate numerical
analyses useful in many scientific fields. It calculates three basic
types of eigenanalysis ordinations: principal components, principal
coordinates, and correspondence/detrended correspondence analyses.
Version 3 adds canonical correspondence analysis, a technique highly
popular in ecological studies. It can also perform cluster analysis,
with 23 different distance and similarity measures and seven
MVSP is in use at hundreds of sites in 86 countries and its results
have been published in numerous scientific journals, including
Science and Nature.
MVSP performs several types of eigenanalysis ordinations: principal
components analysis (PCA), principal coordinates analysis (PCO), and
correspondence/detrended correspondence analysis (CA/DCA). It also
does canonical correspondence analysis (CCA), a technique highly
popular in ecological studies.
It can also perform cluster analysis, using 23 different distance or
similarity measures and seven clustering strategies. A dual
clustering option lets you produce dendrograms of both variables and
cases in one step, along with a copy of the original data matrix,
sorted in the same order as the dendrograms. Constrained clustering
may also be performed, so that the original input data order is
maintained. Diversity indices may be calculated on ecological data;
these include Simpson's, Shannon's, and Brillouin's indices.
The number of cases and variables that can be analyzed is limited
only by the amount of memory available to Windows (RAM and hard disk
swap file), up to a maximum of 2 billion cases and variables.
