\title{Generate a random walk rho trajectory on the Fisher-z scale}
\usage{
rho_random_walk(n_time, z_init = 0.5, sigma_omega = 0.05, seed = NULL)
}
\arguments{
\item{n_time}{Number of time points.}

\item{z_init}{Initial value on Fisher-z scale (default: 0.5, corresponding
to rho = 0.46).}

\item{sigma_omega}{Innovation SD for the random walk (default: 0.05).}

\item{seed}{Random seed for reproducibility.}
}
\value{
Numeric vector of length \code{n_time - 1}.
}
\description{
Stochastic trajectory matching the DC-VAR data-generating process.
}
\examples{
rho_random_walk(100, seed = 42)
