The Interface Between Theory and Data in Structural Equation Models
James B. Grace, Kenneth A. Bollen
2006, Open-File Report 2006-1363
Structural equation modeling (SEM) holds the promise of providing natural scientists the capacity to evaluate complex multivariate hypotheses about ecological systems. Building on its predecessors, path analysis and factor analysis, SEM allows for the incorporation of both observed and unobserved (latent) variables into theoretically based probabilistic models. In this paper...
