<p>So as to move this forward I propose the following course of action.</p>

<p>I shall go through the (now) 144 questions and (1) re-tag any of them with a more appropriate existing tag, and (2) remove the control tag where it seems redundant given the other tags.</p>

<p>If it then seems to me, having read them, that @AdamO's proposed wiki does fit all the ones which are left then I will edit the wiki unless he does it first. If on balance the earlier suggestion from comments on my question, controlling-for-a-variable, seems appropriate i shall come back here and edit this.</p>

<p>======== edit 24 January 2018 ===============</p>

<p>I have now gone through them, deleted redundant tags, re-tagged with more appropriate (mostly <a href="https://stats.stackexchange.com/questions/tagged/quality-control" class="post-tag" title="show questions tagged &#39;quality-control&#39;" rel="tag">quality-control</a>, <a href="https://stats.stackexchange.com/questions/tagged/control-chart" class="post-tag" title="show questions tagged &#39;control-chart&#39;" rel="tag">control-chart</a>) and there remain 95. Of these eight are, I think, about control theory.</p>

<p><a href="https://stats.stackexchange.com/questions/105201/estimating-a-first-order-plus-dead-time-model">Estimating a first order plus dead time model</a></p>

<p><a href="https://stats.stackexchange.com/questions/312717/why-assume-controls-are-independent-of-state-estimation-in-kalman-filter">Why assume controls are independent of state estimation in Kalman Filter?</a></p>

<p>Since control theory is a mystery to me would someone like to confirm that. If they are I propose to re-tag them <a href="https://stats.stackexchange.com/questions/tagged/control-theory" class="post-tag" title="show questions tagged &#39;control-theory&#39;" rel="tag">control-theory</a>. It would then need a wiki.</p>

<p>Of the remainder there are quite a few about control groups and the rest about control variables. I think these are sufficiently distinct in questioners' minds for us to have separate tags. If people agree i will re-tag the control group ones and write a wiki and the remainder can be renamed as a block by someone with the right powers.</p>

<p>============ edit 6 February 2018 ================</p>

<p>This has now been completed with re-tagging and a new tag for <a href="https://stats.stackexchange.com/questions/tagged/controlling-for-a-variable" class="post-tag" title="show questions tagged &#39;controlling-for-a-variable&#39;" rel="tag">controlling-for-a-variable</a> as discussed in comments on the original question.</p>
