<p>The question <a href="https://stats.stackexchange.com/questions/402333/must-know-in-statistics-and-machine-learning">What must someone know in statistics and machine learning?</a> is not suitable for the stats.SE format because it is primarily opinion-based. I believe that much is obvious on its face.</p>

<p>OP's appeal to make this question an exception is premised on a misunderstanding of how this site works. The help center outlines how to ask good questions, and the closure message explains why the question was originally closed. </p>

<p>Making the question community wiki is not a remedy for off-topic content. If it were, we would simply change all off-topic questions to CW; the fact that we do not, but explicitly close them and have robots eventually delete them, suggests that we believe hosting a large volume of off-topic content which continues to attract traffic does active harm to the website. Likewise, community-wiki questions must still be on-topic: <a href="https://meta.stackexchange.com/questions/258006/must-a-community-wiki-post-follow-the-pattern-of-a-qa">Must a community wiki post follow the pattern of a Q&amp;A?</a></p>
