%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) <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>. The CFA/SEM module additionally supports
multi-group invariance testing, latent growth modelling, modification
indices, and path diagram visualisation. Every module can save and restore
an analysis session, export an 'R Markdown' HTML report, and consult an
optional AI assistant that interprets the current results through a
user-supplied large language model API key. Users can upload datasets or
use built-in examples, fit models, compare fit indices, visualize results,
and export outputs without programming.
