Detailed information about the course
Structural Equation Modeling
29 April - 3 May 2019
Dr James Grace, US Geological Service, Lafayette, Luisiana
Natural systems are dynamic and involve many factors which interact and influence each other. This influence can be direct or indirect where effects can be «hidden» and the investigator will miss the importance of such background factors.
Structural Equation Modeling (SEM) is a statistical method to evaluate a priori theory-based models and a statistically more comprehensible alternative to null hypothesis testing. While other statistical techniques such as CCA, PCA or NMDS are rather used to explore multivariate datasets, SEM is used in confirmatory analyses and the evaluation of multivariate hypotheses. It has the capability to look at and distinguish between effects of different factors in one system which makes it possible to investigate multiple hypotheses at the same time. Therefore SEM is a powerful complementary skill to other multivariate techniques for researchers in ecology.
In this workshop the participants will be introduced to the topic and different methods of SEM. The course is a primer on structural equation modelling (SEM) and confirmatory path analysis, with an emphasis on practical skills and application. Theoretical content will be visualized and strengthened by practical exercises. Participants have the possibility to practice on prior to the course prepared datasets but are also encouraged to bring their own data. The used course software is R.
A basic statistics knowledge as well as basic skills in R are a precondition for this workshop
