<p>Hello I am working on your theorem, it would be very helpful if you can clarify some things, :</p>
<p>1. For M', does the apostrophe account for the number of clusters/groups of data? (ie. M''' would be 4 clusters?)</p>
<p>2. When you mention the n-by-n systems, are you referring to systems of linear equations? (ie. 4x4 would be 4 equations, with 4 variables which can possibly represented on a 4 by 4 matrix).</p>

<p>This use of the term "jackknife" is an issue that pops up often. The use of terms may be considered non standard by some but the intent is often clear, as in this case.</p>

<p>Hi Vincent,</p>
<p>I understand the analogy with the multi-purpose knife. I found it confusing because the term "jackknife" already has a different meaning in the context of statistics.</p>

<p>Hi Evelina,</p>
<p>A Jack knife is an all-purpose knife, like a Swiss army knife. My regression is an all-purpse regression (that can be used to do clustering), thus the analogy with Jackknife and the reference to this term.</p>

<p>I find the name "Jackknife regression" confusing. Traditionally, jackknife is a statistical sampling method for variance and bias estimation and the name comes from Tukey, 1958. </p>
