# A question is not displayed in the Linked list, even though it is linked

This question (A): How to write the error term in repeated measures ANOVA in R: Error(subject) vs Error(subject/time) contains a link to this question (B): Specifying the Error() term in repeated measures ANOVA in R, but I do not see question B in the Linked list on the question A page and vice versa.

It looks like the SE software does not "get" that these two questions are linked. Why is that? Is it a bug?

In my experience, the Linked list has always worked as expected.

• Note that the thread is listed in the Related list to the right. – gung - Reinstate Monica Aug 28 '16 at 21:35
• Yes, but these are two different lists; Related is populated automatically with threads that SE software judges most similar to the given one, whereas Linked is populated with all threads that either link to the given one or are linked from it. At least that is what I used to think. – amoeba Aug 28 '16 at 21:37
• I wonder if it's because the link is of the form http://stats.stackexchange.com/questions/51520, rather than the more typical http://stats.stackexchange.com/q/51520/9964 (from the share button) or http://stats.stackexchange.com/questions/51520/specifying-the-error-term-in-repeated-measures-anova-in-r (from the URL bar). – Danica Aug 29 '16 at 1:13
• @Dougal I doubt it. I mostly use this first form (by copying the URL from the address bar and deleting the unnecessary final part of it) and it always worked. – amoeba Aug 29 '16 at 8:55
