abstract: '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) <https://doi.org/10.21105/joss.00978>, LCA through ''poLCA''
  (Linzer & Lewis, 2011) <https://doi.org/10.32614/CRAN.package.poLCA> & ''glca''
  (Kim & Kim, 2024) <https://doi.org/10.32614/CRAN.package.glca>, LTA/IRT via ''mirt''
  (Chalmers, 2012) <https://doi.org/10.18637/jss.v048.i06>, and EFA via ''psych''
  (Revelle, 2025). SEM and CFA functionalities build upon the ''lavaan'' framework
  (Rosseel, 2012) <https://doi.org/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.'
