In the section "Metric" am I right that the "i" across which some of the distance metrics are summed is an index of data dimension? i.e. bivariate data will be i = {1, 2}.

{{Edit COI|D}}
Based on the rough observation of the change logs, the summary table of the 17 linkage criteria has been added on around 2014. On April 26-27, 2024, as there are only 6 linkage criteria with their own Wiki pages. An effort, very new to the Wiki edit requirements, has been made to add a Wiki pages to a linkage criteria. Instead of just deleting the link to this new Wiki page, the existing linkage criteria has been deleted by the Wiki editor as well. Thus, the summary table constructed in 2014 of the 17 linkage criteria has now become 16 linkage criteria.
The main problem of over-deleting the record is that this can be abused by others intentionally to eliminate their competitors, and have the potential to cause serious loss of information for Wiki. Assume that there are three commercial products, A, B, and C, for a biological test experiment listed in Wiki. Supposed that the product A wants to eliminate products B and C in the Wiki list. Simply, product A can do cite-spamming for products B and C. The Wiki Editor will easily notice that there are cite-spamming for products B and C. Thus, in according with the Wiki practice for this page, the Wiki Editor will delete the Products B and C from Wiki. As a result, Product A will become the sole product listed in Wiki for that biological test experiment.
The above imaged case is to highlight that existing records before any possible cite-spamming should not be affected, and should be kept intact. Otherwise, old records as old as ten years can be easily deleted, and people of bad intention may just abuse the Wiki system in another way by using the Wiki Editor to delete their possible competitors in the Wiki.
Looking forward to the attention by the Wiki people who really care about how to do the best practice for the Wiki. It is understood that each organization has its own practices, and someone may not fully understand all these rules very well and thus overlook some rules. Yet, the consequence of over-deleting may become even much more serious than those guys who are just starting the learning process for the Wiki edit functions and still yet to understand all its many rules.

:{{Respond|orangeexclamation|Not done for now:}} <!-- Template:ECOI -->Hi, the same formula is in place for "Hausdorff linkage", from what I can tell from a quick search these terms refer to the same method.
I also noticed that whilst you have submitted a conflict of interest edit request, you have also edited the page. If you do have a conflict of interest with this article please see [[WP:COI]] which recommends against editing the page directly.

:Thanks for your reply and your quick look at this issue. Because this is quick look, it has overlooked the same issue that I raised. I am new to the Wiki edit and try to do some editing on April 26 and 27, 2024. Yet, from around 2014 up to April 26, 2024, there had been 17 linkage criteria in the linkage summary table. This table has been made with the efforts of some very good-hearted volunteer, maybe Wiki editor. There have been an item between the Minimum Variance (MNVAR)[9] and the Hausdorff linkage[10], called Mini-max linkage, between them. One can easily check the existence of this item, and see that this item has not been the product of the incident on April 26-27, 2024. On April 26-27, 2024, just an additional new link has been added to this item, and there are a total of two links for this item. As a new person of Wiki Edit, I do not know that to add a new link may be labeled as cite-spamming. Instead of just deleting the additional link, the whole record of Mini-max linkage, which should have been there when the summary table was set up, has been deleted. This is what I described as over-deleting.
:It seems that just a quick look at the issue has not realized my point about this issue. [[Special:Contributions/223.16.242.216|223.16.242.216]] ([[User talk:223.16.242.216|talk]]) 09:22, 1 May 2024 (UTC)
::Your dates are incorrect, it was added more recently than what you suggest. But that's not really relevant - that content has been in an article for a while does not mean it cannot be altered or removed - Wikipedia's policies grant no special protections to text just because it has been around for a while.

:::Dear MrOllie,
:::Thanks for your reply to my message. Your reply is highly appreciated, as a Wiki Editor will need to take care of many pages voluntarily.
:::In your last message, I am happy to know that, finally there is Wiki Editor to understand that all the 17 items in the summary tables are there before April 26-27, 2024, when I tried to learn the Wiki Edit function and added an additional link to the existing record Mini-max linkage on top of its existing one link. On April 26-27, 2024, before I learn to practice the Wiki Edit function, indeed, I watched a Wiki Edit introductory video, and said that one is welcome to make try this function. Yes, there is the Wiki Editor to decide if the changes are appropriate or not. Nevertheless, the usual practice may be just to restore its changes to the original version, if the editor does not think the changes appropriate.
:::Yet, in this case, at least the record has existed there quite Mini-max linkage some time before April 26-27, 2024, and its existence is independent of the editing of that additional second link. Now, I have a question: why this record was chosen to be delete on the same dates by our Wiki Editor during April 26-27, 2024? It is very easy to think that this deletion of this existing record may be due to over-reacting / over-deleting to the trial to add one more link on April 26-27, 2024. The mathematical structure of Mini-max linkage (which is discovered in 2004) is somehow a little similar to Hausdorff linkage (discovered in 2007). Now the earlier discovered Mini-max linkage is chosen to be deleted by the Wiki Editor, while the later discovered Hausdorff linkage is chosen to be remained there in the table, may I know why there are such difference?
:::Anyway, really thanks for your previous reply out of your voluntary time.
:::It will be highly appreciated if any Wiki Editor can look deeper at this issue to see if there is any logical thinking that can be further improved in this case here. [[Special:Contributions/223.16.242.216|223.16.242.216]] ([[User talk:223.16.242.216|talk]]) 09:13, 10 May 2024 (UTC)
