octane

<p>The octane data contains near infrared absorbance spectra (NIR) of 
    <code>n=39</code> gasoline samples over <code>p=226</code> wavelengths ranging 
    from 1102 nm to 1552 nm with measurements every two nanometers. For
    each of the 39 production gasoline samples the octane number <code>y</code> was measured.
    Six of the samples (25, 26, and 36-39) contain added alcohol.</p>
