    <title>topic Contribution Analysis equation in Adobe Analytics Discussions</title>

    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I was just reading through the Adobe docs regarding contribution analysis and I noticed an "anomaly" (irony intended) in the formula used to calculate Carmer's V stat.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;IMG class="jive-image" src="https://marketing.adobe.com/resources/help/en_US/analytics/analysis-workspace/graphics/cramers-v.png" /&gt;&lt;/P&gt;&lt;P&gt;In the above formula, degrees of freedom has not been accounted for. Given that (C+A) represents the entire dataset, subtracting degrees of freedom from rows and columns is required to account for the constraints that arose in using this data. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I'm assuming that this what the below formula is achieving, however, it's unclear. &lt;/P&gt;&lt;P&gt;&lt;IMG class="jive-image" src="https://marketing.adobe.com/resources/help/en_US/analytics/analysis-workspace/graphics/persons-residual.png" /&gt;&lt;/P&gt;&lt;P&gt;Thanks for your help. &lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
