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.{{cite document|first1=K.R. |last1=Clarke |first2=R.N. |last2=Gorley |year=2015 |title=PRIMER v7: User Manual/Tutorial |publisher=PRIMER-E}} 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){{cite document |first1=M.J. |last1=Anderson |first2=R.N. |last2=Gorley |first3=K.R. |last3=Clarke |year=2015 |title=PERMANOVA+ for PRIMER: Guide to Software and Statistical Methods |publisher=PRIMER-E}}

Routines can be resource intensive due to their non-parametric and permutation-based nature. Programmed in the VB.Net environment.
