<p>There is more to it than simply answering in an affirmative or negative sense.</p>
<p>Since its inception, the community has catered to questions that implicitly needed or explicitly sought derivations/arguments/proofs.</p>
<p>But they were <em>conceptual</em> queries and hence different from  <a href="https://stats.stackexchange.com/questions/tagged/self-study">homework</a> based queries that <em>ask</em> for <em>solving</em> their problems.</p>
<p>The more important thing is how the question is presented: It has to be well-researched. Check books, articles, lecture notes, old CV posts (check for possible duplicates). Then write down</p>
<ul>
<li><p>Your objectives and problems.</p>
</li>
<li><p>What your current understanding points to and whether this or that line of approach is efficient/optimal/problematic or not.</p>
</li>
</ul>
<p>That amplifies your chance of getting a constructive, helpful answer.</p>
<p>Perhaps basic but worth mentioning: a question that shows attempts to understand any available derivation or any relevant effort thereof in laying out a sketch/argument in the same vein is preferable to a question which simply asks to show a proof.</p>
