In case one sees a case of cross-posting, what’s the recommendation? Post a comment saying that cross-posting is against the rules? Or is there a “cross-posting” option in the “vote to close” menu?

I won’t vote to close this one though - I have to admit that cross-posting in this case was useful (I'm putting myself in a dangerous position here ;-P) Ben Bolker’s answer, using NLS, arrives at different results than me using log-transformations plus LS. This is to be expected, since the log weights the residuals for small values of month more than the residual for larger month values. However, I wouldn’t have expected the difference in the estimated curve to be so large.

• There isn't an explicit cross posting close reason, but there is a free text reason under the off topic option. You could do that; if you didn't want to vote to close, you could just leave a comment, & possibly flag to alert the moderators. – gung - Reinstate Monica Jan 10 '18 at 19:41
• While we're asked not to cross post, if it's not off topic I don't think we'd have a basis to close it. When people flag these I generally just leave a comment for the explaining the policy ("Please don't cross post, choose one best site..." etc, pretty much what it says in the help center). If it's a stats question I often vote to close on SO. – Glen_b Jan 11 '18 at 0:53
• @gung I see that in the end it was my answer (or better, the question I answered) that got closed as off-topic, even though it was (IMO) more on-topic here than on CV :-) but I understand - after all, I myself said that I wouldn't flag the other one, and my answer would have never been accepted, thus closing the question on CV was the right choice. – DeltaIV Jan 12 '18 at 7:39
• @DeltaIV, if the version on Stack Overflow gets closed / deleted, & the OP says they want the version on Cross Validated to be the primary Q, I will reopen it. Just let me know. – gung - Reinstate Monica Jan 12 '18 at 18:42
• @gung I don't think it will, but it's ok, don't worry. Ben Bolker's answer deserves to stay open. – DeltaIV Jan 12 '18 at 19:50
