\title{Pool unit-level long-run coefficients via inverse-variance weighting}
\usage{
.pmg_pool_lr(unit_lr)
}
\arguments{
\item{unit_lr}{A list of unit-level results from \code{.csardl_unit_lr()}.}
}
\value{
A list with \code{lr_coef}, \code{lr_se}, and the full pooled
vcov (diagonal).
}
\description{
For each base regressor \eqn{k}, compute
\deqn{\hat\theta^{PMG}_k =
  \frac{\sum_i w_{ik} \hat\theta_{ik}}{\sum_i w_{ik}},
  \quad w_{ik} = 1 / \hat V(\hat\theta_{ik}),}
with pooled standard error \eqn{(\sum_i w_{ik})^{-1/2}}.
