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, 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.
