Multivariate Data Analysis Using PC‑ORD

A short-course on analyzing ecological community data, demonstrated using the PC‑ORD software package.

Upcoming Schedule:

    • Live webinar on Eastern Daylight Time, September 2019 if requested
    • Live webinar 10-12 + 13-15 Eastern Standard Time, 18-22 November 2019
    • Live webinar 10-12 + 13-15 Eastern Standard Time, November 2020

    IMPORTANT:  I will be on sabbatical 1/20-10/20 so NO webinars will be offered during that time.

    Note that the registration deadline is usually 2 weeks in advance of a course to allow for sufficient shipping time for the required book.  Visit the Workshops or Webinars pages for more details.

    About the Course

    This short-course on multivariate analyses, with demonstrations in the PC‑ORD software, has been developed to provide training in three areas:

    1. multivariate analyses common to community datasets (which tools do what);
    2. a 10-step analysis process for defensible analysis and interpretation (how to approach your analysis); and
    3. the PC‑ORD software (through version 7) (how to actually do it).

     

    Tools are introduced, explained, and demonstrated in the order in which you would use them while conducting an analysis.  Topics include:

    • importing, screening, and structuring your dataset(s) prior to analysis
    • exploring and preparing the data for analysis and selecting the appropriate tools
    • guided ordination tools (weighted averaging, polar ordination, CCA, RDA, fuzzy set ordination)
    • free ordination tools (PCA, NMS)
    • classification tools (agglomerative cluster analysis)
    • group-testing tools (MRPP, PerMANOVA, Indicator Species Analysis)
    • association assessment tools (Mantel Test, Fourth Corner Analysis)
    • interpretation, manipulation, and communication of graphics

    Training Options

    • Workshops allow you to attend in person, providing the opportunity to make inquiries about your own data and analyses (and can be hosted at your location).

    • Webinars allow you to attend via the Internet, eliminating travel costs, but are only available if you have reliably high bandwidth (enough to live-stream HD video).

    Instructors

    Trainings are taught by Dr. JeriLynn Peck, who studied with the author of the software (Dr. Bruce McCune) at Oregon State University and has been offering workshops since 1997.  Dr. Eric K. Zenner, with a background in applied univariate statistics, sometimes provides assistance.

    Fees

    Registration fees for most trainings are in the $450-$500 range, with lower fees for students (~$250) and workshop hosts.  This fee does not include the software or companion book, which must be ordered from the software distributor.  Payment for the workshop fee is accepted in the form of checks made out to "Penn State" or by credit card.  Certificates of completion are available upon request.

    Short-course or Self-study?

    If you are self-driven, you may be able to successfully work through the required companion book on your own.  If you are in a hurry, however, or learn best by doing/listening rather than reading, then a short-course may be best for you.  Not sure?  Order a copy of the companion book now and try reading through it on your own; then, if you decide to attend a short-course, you'll already have it and be able to sign up on short notice.

    About PC‑ORD

    We are not affiliated with the software company.  We use it for the demonstrations, however, because as one of the few statistical packages specifically designed for community analyses, PC‑ORD brings together in one place many relevant analyses that are otherwise only found scattered among different software packages.  Further, because PC‑ORD was written with community ecologists in mind, it includes several procedures and options that are best suited for species data yet found nowhere else.  Current trainings cover procedures available in PC‑ORD version 7, but because later versions of PC‑ORD build on previous versions, everything in version 6 will be covered during the training--plus additional features in version 7.  Thus, if you have not updated to version 7, everything in versions 5 and 6 will be covered plus there will be some new tools introduced that you don't yet have.
