projectLSA-package

Provides an interactive Shiny-based environment for performing Latent Profile
Analysis (LPA), Latent Class Analysis (LCA), Latent Trait Analysis (LTA; IRT),
Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and
Structural Equation Modeling (SEM). All analyses are conducted through a
graphical user interface without requiring users to write code.
This file records package-level imports for roxygen2 so that NAMESPACE
will include the appropriate import directives.

Provides an interactive Shiny-based toolkit for conducting latent structure analyses, including Latent Profile Analysis (LPA), Latent Class Analysis (LCA), Latent Trait Analysis (LTA/IRT), Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). The implementation is grounded in established methodological frameworks: LPA is supported through 'tidyLPA' (Rosenberg et al., 2018) <doi:10.21105/joss.00978>, LCA through 'poLCA' (Linzer & Lewis, 2011) <doi:10.32614/CRAN.package.poLCA> & 'glca' (Kim & Kim, 2024) <doi:10.32614/CRAN.package.glca>, LTA/IRT via 'mirt' (Chalmers, 2012) <doi:10.18637/jss.v048.i06>, and EFA via 'psych' (Revelle, 2025). SEM and CFA functionalities build upon the 'lavaan' framework (Rosseel, 2012) <doi:10.18637/jss.v048.i02>. Users can upload datasets or use built-in examples, fit models, compare fit indices, visualize results, and export outputs without programming.
