\usage{
check.data(y, x1 = NULL, x2 = NULL)
}
\arguments{
\item{y}{time series y in matrix format (\code{n} rows x 2 columns). The
first column should contain the time steps and the second column should
contain the values.}

first column should contain the time steps and the second column should
contain the values.}

\item{x2}{time series x2 in matrix format (\code{n} rows x 2 columns). The
first column should contain the time steps and the second column should
contain the values.}
}
\value{
Returns a named list containing:
\item{t}{time steps}
\item{dt}{size of a time step}
\item{n.obs}{number of observations}
}
