Split testing with weighting
<p>I am looking to figure out how to use a database of sales completions to influence split testing.</p>

<p>For example, say I have four different page layouts and for each I have the following stats:</p>

<ul>
<li>Version 1: 6 sales,</li>
<li>Version 2: 1 sale,</li>
<li>Version 3: 3 sales,</li>
<li>Version 4: 4 sales,</li>
</ul>

<p>Then it would make sense to have version 1 shown most often, and version 4 being next, while version 2 should hardly be shown at all.</p>

<p>Any ideas how I can achieve this?</p>
