Besides the questions on our site, there's already Computer science, Artificial Intelligence and Data Science (all of which have questions on neural networks - and that's not even counting the neural networks questions on StackOverflow and on Theoretical Computer Science ...). I'm not sure that adding a fifth (or seventh ...) site fielding questions on the ...

On-topic: Terminology As long as it's statistical terminology, I say it's on topic. Lots of statistical ideas have multiple names.

On-topic: Notation Notation questions should be on-topic. Notation is critical; it is also often hard to search for. I would be generous with notation that is used in multiple fields such as math and statistics.

On-topic: Machine learning questions Note: This criterion is currently accepted per this post and this post unless it falls below 0 votes. No special criteria regarding this topic have been specified. No criteria have been excluded for this topic

I view data cleaning as on-topic here: it is a fundamental, if somewhat unglamorous (and underappreciated) aspect of data analysis. But, in keeping with this site's approach and philosophy, we would want to welcome answers that focus on principles and generalities which would apply regardless of one's computing platform, and migrate any threads that ...

The official statement of what is on-topic on CV is that we address questions about: statistical analysis, applied or theoretical designing experiments collecting data data mining machine learning visualizing data probability theory mathematical statistics statistical and data-driven computing It is OK if ...

I think the decision to migrate my question reflects an over-zealous concern by the moderators for maintaining a strict separation from SO. Questions about software are appropriate on CV. The FAQ (I wrote the first version) includes "statistical and data-driven computing". Asking what package implements a specific procedure falls directly into that category. ...

On topic: Program specific questions (e.g. R, SAS, SPSS, Matlab, C++, python, etc) with any statistical content Note: This criterion is currently accepted per this post and this post unless it falls below 0 votes. Answer the question unless it clearly has no statistical content. No other special criteria regarding this topic have been accepted No criteria ...

I often, but not always, vote to close many such questions. Why? There is no axiom that all questions have a place somewhere on SE. Questions on the routine use of some language don't belong here and they don't belong on SO if they are not about a (non-trivial) programming problem raised by the poster's own code. For example, questions about "How do I do X ...

This is a (lightly edited) composition of the comments left above by @Scortchi, @whuber, @Glen_b, and Roland (I am marking this answer as CW). I believe they fully answer this question. There is no practical distinction between "focus on" and "about". Migration occurs when the question is likely to be considered on topic at the ...

The migration dialog provides a short list of target sites. These are the sites all users may choose as likely targets. Because it's important to get along with other sites, it is crucial that all our users with vote-to-migrate privileges well understand the on-topic criteria at those sites. For years the only options have been SO, Math, and our own Meta ...

@whuber is right. When I judge that questions would be viable on SO, I'm happy to migrate. But most of the programming-ish questions I see don't seem good enough. In particular, they tend to lack reproducible examples. It's also worth being clear that a, say, 'how do I use R?' question would be off topic here, and can simultaneously be off topic on SO as ...


11

I didn't know this, but we are limited to only 3 migration targets. It makes the most sense to allocate these 3 slots to the 3 most prevalent targets, which I assume are Meta.Stats.SE, Math.SE and SO.SE.

I would say they are on-topic, but perhaps still likely to get closed here (either as not a real question or duplicate, depending on the circumstances), unless there is some additional context provided by the author. The distributions tag will bring up some examples. This search narrows things down a little more.

Question (Cleaned up version from a real question: https://stackoverflow.com/q/11941178/892313) I have a data.frame with numeric columns. How can I write it to a file, using write.table, such that R writes the full number 40000000 instead of 4e+07? Issues No statistical issues, so Off Topic on CV. It does involve programming issues, so it is on topic ...

Software-specific questions have always been a touchy subject here. When questions are only about how to do something in R, or what does this error message mean, or what is the code for, or what is the package for, are off-topic for CV. However, it can be tricky. For what it's worth, my rule is simple: what does the OP need explained? If it is a ...

I have made st.statistics a synonym of mathematical-statistics (which is not an intrinsic tag) and pr.probability a synonym of probability. Please keep an eye on attempted migrations from MO and let us know whether there are any more problems with them.

On topic: Questions that require statistical reasoning to be answered correctly For example, someone asking for help debugging code that is obviously the wrong solution to their actual problem. Note: This criterion is atypical because it is a property based on the answer rather than the question itself. If approved this criterion may be difficult to ...

Well done Glen for sorting this out! I think the OP in fact got good advice in the very first comment—to clarify their question, that questions purely on programming are for SO, & even what function to look into using—but they didn't know how to act on it. One, hopefully uncontroversial, lesson we can learn from this straight away is to take ...

This is not a particularly great question for Stack Overflow. I wouldn't necessarily have closed it if it had been asked there, but given it was originally asked here and arguably isn't wholly inappropriate I'm not going to waste time trying to re-write it to fit somewhere else - y'all can edit / answer / close / continue discussing as you feel appropriate. ...

I voted to migrate this question after some thought and reviewing the comments; this was not a clear or automatic case. I ultimately relied on the original text to make the decision for me: it explicitly asks for a Python solution and the OP takes pains to intimate that he could program the algorithm himself, but wishes to avoid it. That was a sufficiently ...

I would suggest first consulting What should I do if nobody answers my question? in the help pages. Failing that, simply flag your post for moderator attention. Explain you would like it migrated (and suggest the destination).

What happens to reputation if an upvoted answer is moved to another SE site? The answer is deleted in the source site and the reputation is revoked. Votes are migrated to the target site with their respective posts, and if the answer's author has an account there, it will receive the associated reputation. If a question which received some upvotes is ...

Despite the close vote reason ('programming issue', which is the default message actually, see below), there's nothing in your question that would look like a statistical issue. As such it is off-topic and it might be better served on another site (certainly not Super User where there seems to be limited interest for R compared to, say, Stack Overflow where ...
