PC-ORD is
BIO-LOGICAL
Over 5,000 articles in biology journals contain
graphs & multivariate analyses produced by PC-ORD |
PC-ORD performs multivariate analysis
of ecological data entered in spreadsheets. Our emphasis is on nonparametric tools,
graphical representation, randomization tests, and bootstrapped confidence intervals for
analysis of community data. In addition to utilities for transforming data and
managing files, PC-ORD offers many ordination and
classification techniques not available in major statistical packages including: CCA, DCA,
Indicator Species Analysis, Mantel tests and partial Mantel tests, MRPP, PCoA, perMANOVA,
RDA, two-way clustering, TWINSPAN, Beals smoothing, diversity indices, species lists, many
ordination overlay methods (quantitative, symbol-coding, color-coding, grid, joint plot,
biplot, successional vector), various rotation methods, 3-D ordination graphics,
Bray-Curtis ordination, city-block distance measures, species-area curves, tree data
summaries, publication-quality dendrograms, autopilot mode nonmetric multidimensional
scaling (NMS or NMDS). Very large data sets can be analyzed. Most operations
accept a matrix up to 32,000 rows or 32,000 columns and up to 536,848,900 matrix elements,
provided that you have adequate memory in your computer. The terminology is tailored
for ecologists. The full manual is included as a context-sensitive help system.
