Title: Latent Structure Analysis Toolkit
Version: 0.0.3
Description: 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), 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.

Latent Structure Analysis Toolkit

Description

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.

Main Function

The primary entry point is run_projectLSA, which launches the full interactive application.
