<p>Currently the <a href="https://stats.stackexchange.com/help/on-topic">Help Center > Asking</a> states that questions are on-topic if they're about "statistical analysis, <em>applied or theoretical</em>", and whenever it's about programming "if it needs statistical expertise to understand or answer". This also is the topic of <a href="https://stats.meta.stackexchange.com/q/2007/163114">this meta discussion</a>. </p>

<p>Shouldn't therefore questions concerning the implementation of a particular statistical model in different software be <strong>on-topic</strong> on Cross Validated (CV)?</p>

<p><strong><em>What happened:</em></strong> A few days ago I encountered the problem of how a specific statistical "far from trivial" model can be implemented in R rather than in Stata. Google's results were rare and one pointed me straight to <a href="https://stats.stackexchange.com/q/397488/163114"><strong>this question on CV</strong></a> which gave me valuable hints, but the solution was not provided. I had to do quite an amount of extra research and after I found a solution, and after I've convinced myself that the same statistical method is being used, I wrote an <a href="https://stats.stackexchange.com/a/402429/163114">answer</a> to share my insights with the OP and the community.</p>

<p>Just after I've posted my answer, the question was closed as <strong>off-topic</strong>. I am wondering why, since the OP has written his question in a "general format" and elucidates "underlying statistical methods" as demanded in <a href="https://stats.meta.stackexchange.com/q/5586/163114">this meta discussion</a>. </p>

<p>Rather, perhaps my answer is somewhat off-topic, as it does not contain much statistical explanation.
The question hasn't been migrated to Stack Overflow (SO), since it might be a "<em>borderline</em> question" in terms of <a href="https://stats.meta.stackexchange.com/a/2009/163114">@Shog9</a>. IMO it therefore shouldn't have been closed on CV. </p>

<p><strong><em>My point</em></strong> is that on CV answers to questions about how a certain statistical model <em>X</em> can be implemented in software <em>Y</em> (perhaps with an unknown package <em>Z</em>) are often invaluable. I personally doubt to get statistically valid answers on Software Recommendations or r-help - as some <a href="https://stats.meta.stackexchange.com/q/2418/163114">suggest where to ask such questions</a> - when things enter non-trivial statistical areas. I would most likely trust answers or consider them significant if they are right here on CV. There are several other similar questions which are not closed, e.g.: <a href="https://stats.stackexchange.com/q/6469/163114">1</a>, <a href="https://stats.stackexchange.com/q/400223/163114">2</a>, <a href="https://stats.stackexchange.com/q/401723/163114">3</a>,
<a href="https://stats.stackexchange.com/q/378105/163114">4</a>,
<a href="https://stats.stackexchange.com/q/96657/163114">5</a>. I have found several of them to be really useful. Some such questions would be off-topic on SO since they are "too broad", for example <a href="https://stackoverflow.com/q/5114782/6574038">this question</a>, or doesn't contain a MCVE, for example <a href="https://stackoverflow.com/q/55555492/6574038">this question</a>. Further asking to "recommend or find a book, tool, software library, tutorial or other off-site resource" is off-topic on SO as also noted in <em>@Tim</em>'s <a href="https://stats.meta.stackexchange.com/q/2418/163114">CV meta question</a>. </p>

<p><em>I consider CV as an invaluable resource of such model implementation questions in different software and I would be disappointed to see that to change.</em></p>

<p><strong><em>I'm aware</em></strong> that this topic has its history. Maybe my question contributes to some further differentiation (from e.g. pure programming R questions). <a href="https://stats.meta.stackexchange.com/a/4590/163114">This answer</a> doesn't fit to the type of questions since it doesn't cover model implementation in different software. </p>

<p>Also <a href="https://stats.meta.stackexchange.com/a/795/163114">this community wiki</a> isn't suitable to the question since it is not purely software-related and needs a statistically educated brain to give an adequate answer which can't be a entry on a simple package list.</p>
