Structural Equation Modelling for Ecologists and Evolutionary Biologists 
(SEMR02)

https://www.prstatistics.com/course/structural-equation-modelling-for-
ecologists-and-evolutionary-biologists-semr02/

This course will be delivered by Jon Lefcheck (author of the piecewise 
package) in Glasgow City Centre from 19th - 23rd November 2018.

Course Overview:
The course is a primer on structural equation modelling (SEM) and 
confirmatory path analysis, with an emphasis on practical skills and 
applications to real-world data.

Structural equation modelling is a rapidly growing technique in ecology and 
evolution that unites multiple hypotheses in a single causal network. It 
provides an intuitive graphical representation of relationships among 
variables, underpinned by well-described mathematical estimation 
procedures. Several advances in SEM over the past few years have expanded 
its utility for typical ecological datasets, which include count data, 
missing observations, and nested or hierarchical designs.

We will cover the basic philosophy behind SEM, provide approachable 
mathematical explanations of the techniques, and cover recent extensions to 
mixed effects models and non-normal distributions. Along the way, we will 
work through many examples from the primary literature using the open-
source statistical software R (www.r-project.org). We will draw on two 
popular R packages for conducting SEM, including lavaan and piecewiseSEM.
Participants are encouraged to bring their own data, as there will be 
opportunities throughout the course to plan, analyze, and receive feedback 
on structural equation models.
