\title{Centred Random Generation from the Arvind Distribution}
\usage{
rarvind_centred(n, theta)
}
\arguments{
\item{n}{positive integer; number of random variates to generate.}

\item{theta}{positive numeric scalar; the distribution parameter.}
}
\value{
A numeric vector of length \code{n} with approximately zero mean.
}
\description{
Generates centred Arvind variates with approximately zero mean, suitable
for use as error terms and innovation terms in stochastic regression models.
}
\details{
The centred variate is computed as \eqn{\tilde{\varepsilon} =
\varepsilon - \mu_A(\theta)}, where \eqn{\varepsilon \sim
\mathrm{Arvind}(\theta)} and \eqn{\mu_A(\theta)} is the mean of the
Arvind distribution.
}
\examples{
set.seed(42)
eps <- rarvind_centred(1000, theta = 2)
mean(eps)  # approximately 0
