Plymouth Routines In Multivariate Ecological Research (PRIMER) is a statistical package that is a collection of specialist univariate, multivariate, and graphical routines for analyzing species sampling data for community ecology.
Types of data analyzed are typically
species abundance
In ecology, local abundance is the relative representation of a species in a particular ecosystem. It is usually measured as the number of individuals found per sample. The ratio of abundance of one species to one or multiple other species livin ...
, biomass, presence/absence, and percent area cover, among others. It is primarily used in the scientific community for ecological and environmental studies.
Multivariate routines include:
*grouping (CLUSTER)
*sorting (MDS)
*principal component identification (PCA)
*hypothesis testing (ANOSIM)
*sample discrimination (SIMPER)
*trend correlation (BEST)
*comparisons (RELATE)
*diversity, dominance, and distribution calculating
* Permutational multivariate analysis of variance (
PERMANOVA)
Routines can be resource intensive due to their non-parametric and permutation-based nature. Programmed in the VB.Net environment.
