%description
Provides an iterative optimization algorithm for exploratory and
confirmatory factor analysis that follows a boosting approach inspired by
machine learning. It uses a composite fit index whose weights adapt to the
degrees of freedom and the sample size, following Kenny and McCoach (2003)
<doi:10.1207/S15328007SEM1003_1> and Shi, Lee and Maydeu-Olivares (2019)
<doi:10.1177/0013164418783530>. It detects and removes problematic items
(Heywood cases, cross-loadings, low loadings) with greedy or global search
strategies, checks interfactor correlations, and supports ordinal data
with WLSMV estimation and several rotation methods. A heuristic
specification search for confirmatory models (MacCallum, 1986
<doi:10.1037/0033-2909.100.1.107>) explores move, drop and covariance
operations across seed configurations. It also evaluates the resampling
stability of the item selection, the recovery of a known or theoretical
structure, and offers an optional conceptual analysis of removed items
through a large language model service.
