\title{Polynomial distributed lags}
\description{
Creates a regressor matrix for polynomial distributed lags.
}
\usage{
pdl(x, d = 2, q = 3, trim = FALSE)
}
\arguments{
\item{x}{
a numeric vector.
}
\item{d}{
an integer specifying the order of the polynomial.
}
\item{q}{
an integer specifying the number of lags to use in creating
polynomial distributed lags. This must be greater than \code{d}.
}
\item{trim}{
a logical flag; if \code{TRUE}, the missing values at the beginning
of the returned matrix will be trimmed.
}
