Are very elementary questions off topic on CrossValidated?

To my mind, elementary is too slippery a criterion for closing. I don't doubt there are many questions that are elementary for @MichaelChernick that would be over my head, and I don't necessarily ...

Should questions about comparing the output from different statistical software be on topic here?

I would lean towards allowing such questions. For example, I answered such a question here: Difference in output between SAS's proc genmod and R's glm. My general position is that whether a question ...

Dealing with "do my professional work for me" questions?

I downvoted your question because the part about job-related questions doesn't make sense, and it's unrelated to the site policy: this is a Statistics Q&A - nowhere in the list of questions one ...

Policy on questions that read like, "How should I do my job?"

A question should be judged based on whether it is a good statistics problem. Statistics are used in business, in academic research, in politics, in volunteer activities, and by some really weird ...

Overlap with ai.stackexchange and datascience.stackexchange

"Help I have some data and need to analyse it what do I dooo?"

I'm sorry, but I don't think this is a useful approach. The questions you are referring to are essentially "please teach me data science". There are just far too many possible flavors. If you set up ...

Does advanced probability theory belong on stats or math stackexchange?

At what point is a question concerning probability abstract enough that it is more appropriate on the math stackexchange instead of crossvalidated? I don't think there's necessarily a point at which ...

Where to learn about R packages?

The answer is, of course, "it depends", but I think you're asking about something different from what you think you're asking about. I believe we can all agree that a question like Is there an R ...

Would Cross Validated want Machine Learning Theory questions that are no longer on-topic for Stack Overflow?

They should be migrated here! Already two comments prefer option 1) so that looks a good one.

What to do about "wrong" questions?

As a beginning user, I would like to give my opinion on this and why I strongly favour (3) if it is possible to write such an answer clearly. An example where I learned a lot from reading a "wrong" ...

"Help I have some data and need to analyse it what do I dooo?"

The endless variations on "How do I analyze these data?" are not answerable questions. Full stop. When I first started my career, I worked as a consultant specializing in data science. I didn't know ...

Are questions about ethical use of statistics on-topic?

I don't believe there's any precedent for ruling such questions out of scope. Their requiring statistical expertise to answer would be the general principle under which they're in scope. The kind I ...

Should the mailing list on structural equation modeling (SEMNET) consider moving to CV?

SEMNET should just consider posting questions on stats.stackexchange.com, tag them sem or latent-variable or whatever, and their experts should register and answer these questions.

If OP asks for a software referral, and a referral *doesn't* exist, may we answer with the code they asked for?

If code is the full answer to a question, then the question is off-topic. When the code illustrates or implements a statistical answer, such as a procedure or algorithm offered in response to a ...
