Package: pwSEM Title: Piecewise Structural Equation Modelling Version: 1.0.0 Authors@R: person("Bill", "Shipley", , "Bill.Shipley@USherbrooke.ca", role = c("aut", "cre"), comment = c(ORCID = "0000-0002-7026-3880")) Description: Conduct dsep tests (piecewise SEM) of a directed, or mixed, acyclic graph without latent variables (but possibly with implicitly marginalized or conditioned latent variables that create dependent errors) based on linear, generalized linear, or additive modelswith or without a nesting structure for the data. Also included are functions to do desp tests step-by-step,exploratory path analysis, and Monte Carlo X2 probabilities.
