eLTER SPF time series analysis workshop

The eLTER SPF Training working group organised its first workshop. Based on the questionnaire results on training needs from sites, this workshop focused on time series analysis, given by Ulrike Obertegger (FEM-CRI, Italy).

The workshop was open to everyone from students to researchers, independently of involvement in eLTER projects. The workshop gave an introduction to the challenges of time series data and demonstrate different analysis methods. This was not a technical course but a practical demonstration of what can be done to solve certain ecological questions.

All the analyses are done in R and thus a basic understanding of R coding is helpful but not necessary.

Outline:

• Welcome by eLTER Coordinators Michael Mirtl (UFZ) and Jaana Bäck (UH)
• Introduction on basic terminology
• Classic time series analyses. Mann Kendall, Sen Theil trend estimation
• Change point analysis
• Modeling time series with cosine trends
• GAM
• Clustering of time-series with DTW

R-script and example data were provided one week before the workshop. Please note that several R packages, as outlined in the R-script, have to be uploaded to make everything work.
