Jan 17, 2023 at 21:08 comment added Iosif Pinelis I see now. I will try to remember this and, when suitable, indicate the kind of source in the title.
Jan 17, 2023 at 20:44 comment added fedja @IosifPinelis I mean that when I click on your profile and use "all questions" option to get the multipage list of question titles alone (not the actual posts, there you do make a clear distinction but I need to click on the titles one by one to get there) I cannot tell at a glance which is which.
Jan 17, 2023 at 18:21 comment added Iosif Pinelis "you don't create any distinction between this situation and the situation when you ask something you are interested in" -- I am not sure what you mean here. Whenever I ask a question (even if previously asked by someone else and then deleted), I am interested in it, to some degree. Also, whenever I ask a question and can answer it, I would answer it. Also, when I revive a question previously asked by someone else, I always try to make the origin of the question quite clear. So, I am not sure what you mean by "you don't create any distinction".
Jan 17, 2023 at 17:58 comment added fedja @IosifPinelis I'm inclined to stick to my claim, but thank you very much for fixing the stupid typos anyway! Anything else you want me to look at? BTW, you have one habit that I do mind: when you retype somebody else's question and then answer it yourself, you don't create any distinction between this situation and the situation when you ask something you are interested in, so finding the actual questions of yours in that stream is quite an exercise. Some relevant note in the question title would certainly help ;-)
Jan 17, 2023 at 16:16 comment added Iosif Pinelis In my view, neither is the case. :-) I made a corresponding comment on your "copula" answer there.
Jan 17, 2023 at 13:50 comment added fedja @IosifPinelis Then either I misunderstand something, or it is trivial. Let me know which one is the case (I posted an answer in that thread).
Jan 17, 2023 at 4:08 comment added Iosif Pinelis I meant to say, a copula is the joint cdf of two random variables each uniformly distributed on $[0,1]$.
Jan 17, 2023 at 3:32 comment added Iosif Pinelis A copula is the joint cdf of two uniformly distributed random variables. The Frechet--Hoeffding upper bound is, I think, the copula $C(u,v)=\min(u,v)$ for $u,v$ in $[0,1]$.

Jan 17, 2023 at 2:16 comment added fedja @IosifPinelis Yes, if you or somebody else translates it into the language I can understand (I know neither what copula is, nor what the Frechet-Hoeffding upper bound refers to and google search is definitely not my favorite thing)
