%description
Estimates structural equation models by case-based least squares: the
latent scores of every observation are treated as free variables of a
constrained optimization problem, so that arbitrary nonlinear model
equations, bounds and constraints on latent variables and inequality
constraints on parameters become possible.  Model equations are specified
as plain text (e.g. "y == a*exp(b*eta)"). Gradients are obtained by
automatic differentiation via 'RTMB', and the constrained problem is
solved with 'nloptr' (SLSQP or augmented Lagrangian).  Missing data are
handled case-wise.  The methodology is described in Oldenburg (2024)
<doi:10.19139/soic-2310-5070-1868> and Oldenburg (2025)
<doi:10.19139/soic-2310-5070-2324>.
