piecewiseSEM : Piecewise structural equation modelling in r  for ecology, evolution, and systematics

Summary Ecologists and evolutionary biologists rely on an increasingly sophisticated set of statistical tools to describe complex natural systems. One such tool that has gained significant traction in the biological sciences is structural equation models ( SEM ), a form of path analysis that resolves complex multivariate relationships among a suite of interrelated variables. Evaluation of SEM s has historically relied on covariances among variables, rather than the values of the data points themselves. While this approach permits a wide variety of model forms, it limits the incorporation of detailed specifications. Recent developments have allowed for the simultaneous implementation of non‐normal…
