ozone

<p>Los Angeles ozone pollution data, 1976.  
We deleted from the original data, the first 3 columns which were the  
<code>Month</code>, <code>Day of the month</code> and <code>Day of the week</code>. Each
observation is one day, so there is 366 rows.
The <code>ozone</code> data is a matrix with 9 columns.</p>
