</h2>
<p>To apply the introduced methods the dataset <code>voltage</code> is
used. The dataset contains observations for units that were passed to a
high voltage stress test. <em>hours</em> indicates the number of hours
until a failure occurs or the number of hours until a unit was taken out
of the test and has not failed. <em>status</em> is a flag variable and
