<p>Note that in some cases a post can be on topic at more than one site. Generally you should just choose the best one (which may relate to the kind of answers you seek).</p>

<p>In other cases a post may be excluded from the scope of one or even both sites, in spite of the fact that you think it should belong there.</p>

<p>Our <a href="https://stats.stackexchange.com/help/on-topic">help/on-topic</a> page discusses the scope of our site in some detail. See the opening section and the later part that mentions <em>programming</em>.</p>

<p>In particular, to be on topic here a question should be statistical in nature, rather than be about implementation details in some language. If you want to compare two algorithms, it <em>might</em> be on topic. If you want to compare two code-blocks, it's likely off topic here. </p>

<p>If your question relates to an error message it's almost certainly off-topic here (with some exceptions where the underlying issue is a clearly statistical one). </p>
