  "Description": "Provides an interactive Shiny-based toolkit for conducting\nlatent structure analyses, including Latent Profile Analysis\n(LPA), Latent Class Analysis (LCA), Latent Trait Analysis\n(LTA/IRT), Exploratory Factor Analysis (EFA), Confirmatory\nFactor Analysis (CFA), and Structural Equation Modeling (SEM).\nThe implementation is grounded in established methodological\nframeworks: LPA is supported through 'tidyLPA' (Rosenberg et\nal., 2018) <doi:10.21105/joss.00978>, LCA through 'poLCA'\n(Linzer & Lewis, 2011) <doi:10.32614/CRAN.package.poLCA> &\n'glca' (Kim & Kim, 2024) <doi:10.32614/CRAN.package.glca>,\nLTA/IRT via 'mirt' (Chalmers, 2012)\n<doi:10.18637/jss.v048.i06>, and EFA via 'psych' (Revelle,\n2025). SEM and CFA functionalities build upon the 'lavaan'\nframework (Rosseel, 2012) <doi:10.18637/jss.v048.i02>. The\nCFA/SEM module additionally supports multi-group invariance\ntesting, latent growth modelling, ordinal indicators estimated\nfrom polychoric correlations, modification indices, and path\ndiagram visualisation. Every module can save and restore an\nanalysis session and export an 'R Markdown' HTML report whose\nsections can be drafted with an optional AI assistant. The\nassistant interprets the current results through one or several\nlarge language models reached with user-supplied API keys,\nincluding providers with a free tier. The application runs in a\nresponsive HTML interface. Users can upload datasets or use\nbuilt-in examples, fit models, compare fit indices, visualize\nresults, and export outputs without programming.",
