shipley

data

Implements piecewise structural equation modeling from a single
list of structural equations, with new methods for non-linear, latent, and
composite variables, standardized coefficients, query-based prediction and
indirect effects. See <http://jslefche.github.io/piecewiseSEM/> for more.
