\title{Post-Estimation Utilities for 'lavaan' Fitted Models}
\description{
\if{html}{\figure{logo.png}{options: style="float: right; margin: 0 0 8px 12px;" alt="lavinteract logo" width="110"}}

Post-estimation tools for structural equation models fitted with 'lavaan'.
Provides methods for probing observed and latent interactions, diagnosing local
misfit and multicollinearity, quantifying incremental effect sizes for 
structural predictors, assessing predictive performance by repeated holdout 
cross-validation, and adjusting selected parameter p-values for multiple 
testing. Functions operate from a fitted model object and, when needed, refit 
auxiliary or reduced models while preserving the original SEM specification.

\details{
The functions are:
\itemize{
  \item \code{\link{lav_slopes}}: simple slopes and interaction plots from a fitted 'lavaan' model.
  \item \code{\link{lav_jn}}: Johnson-Neyman regions of significance for continuous moderators in a fitted 'lavaan' model.
  \item \code{\link{lav_deltaR2}}: incremental effect sizes (part \eqn{R^2} and Cohen's \eqn{f^2}) for structural predictors via reduced-model comparisons.
  \item \code{\link{lav_localfit}}: residual-based local fit diagnostics and heatmaps for fitted 'lavaan' models.
  \item \code{\link{lav_vif}}: variance inflation factors for structural predictors with measurement preserved.
  \item \code{\link{lav_cv}}: repeated holdout (Monte Carlo) cross-validation of \eqn{R^2} for SEM outcomes.
  \item \code{\link{lav_fdr}}: false discovery rate correction for selected 'lavaan' parameter p-values.
}

\section{Note}{

The development of this package grew from ongoing discussions and interactions (sic)
with colleagues, in particular Dr. Cataldo Giuliano Gemmano, whose steady 
feedback and support helped shape it.
