\title{Delta Method}
\usage{
.delta_method(g, b, V, h = 1e-06)
}
\arguments{
\item{g}{A function of the parameter vector returning the transformed values.}

\item{b}{Numeric vector: parameter estimates.}

\item{V}{Numeric matrix: variance-covariance of \code{b}.}

\item{h}{Numeric: step size for numerical differentiation. Default \code{1e-6}.}
}
\value{
A list with \code{estimate} (transformed values) and \code{vcov} (delta-method
variance).
}
\description{
Computes standard errors for nonlinear transformations of parameters
using the delta method: \verb{V(g(b)) = G' V(b) G} where \code{G = dg/db}.
