| I am not competent to estimate this myself but I assume you guys are if I can find info such as the number tagged each month. If this is the wrong place to ask for a statistical estimate where should I ask please? ] (]) 17:43, 5 September 2024 (UTC) | |||
| I noted in the example on the 1age standardisation' entry that the heart disease rates amongst indigenous Australians ae compared to the general population and to the overall population. Are the general population and the overall population the same? | |||
| == Which countries/territories should be included == | |||
| This article seems confusingly written. How can patients who have not completed the design be included in the assessment of efficacy? How can patient dropout break the initial randomization? These are concepts that sound like nonsense unless further explained. Certainly, dropout may be greater in the treatment group due to more severe side effects, but the dropout rate should be the same in the control group, and in any case it is not clear that the side effects should be correlated with the treatment effect. Including untreated patients in the assessment of treatment efficacy is certain to bias against the efficacy measure, so this is an overreaction strategy that seems entirely unnecessary in a proper experimental design with a placebo control group. ---- | |||
| ] - (This article is listed as Mid-importance on the Statistics WikiProject.) | |||
| == Should the curve and surface fitting web site zunzun.com be discussed anywhere in Misplaced Pages? == | |||
| A difference of opinion has arisen on which countries/territories should be ranked on this article. Specifically, whether all countries/territories should be ranked, or only UN member states. | |||
| Should the curve and surface fitting web site zunzun.com be discussed anywhere in Misplaced Pages? It seems relevant to some of the statistics topics. | |||
| The section is titled "''Sovereign states and dependencies by population''". From this title, it's unclear whether disputed states / territories (e.g. Taiwan, Kosovo, Palestine) should be included. | |||
| Links to zunzun.com are banned from Misplaced Pages. Such discussions are useless no matter how relevant. | |||
| The previous version of this article excluded disputed territories in the ranking, but '''also''' excluded dependencies (despite the section title). Presumably this decision was made by a previous editor, because dependencies are not UN members, and only UN members were ranked in the previous article version. | |||
| == Category rename == | |||
| Column 1 of the table retains the UN member-only ranking, which was the only ranking shown in the previous version of this article. | |||
| There is a discussion of renaming category ] to ]: see and contribute in this | |||
| ''']'''. | |||
| My recent edit added column 2 to the table, which ranks all countries/dependencies. | |||
| == Two envelopes problem, two children problem == | |||
| I opted to keep both columns rather than replace, to take a more conservative/inclusive approach. Discussion has been on whether to have only 1 ranking column, and if so, which to rank. One editor reverted the article to UN members-only ranking without discussion, but I have restored both columns and requested further discussion on the talk page. | |||
| Having fought for two years on the Monty Hall problem, almost getting banned from wikipedia for OR and COI, I am looking for a new brawl, and am getting stuck into the ]. Have been accused of gross arrogance and incivility within one day (practice makes perfect! I didn't want to waste time with ritual dances but went straight to the nitty gritty). There is a big problem with that page, that a lot of people have been writing up their own common sense solutions (both sensical and nonsensical) but almost no one actually reads the sources. I just wrote up two mainsteam solutions to two main variants of the two envelopes problem, both "out of my head", ie without reliable sources. (Very evil of course, very un-wikipedian). After all, I have been talking about these problems with professional friends for close on fourty years now, and setting them as exam questions, talking about them with students, without ever actually carefully reading published literature on the problems. | |||
| :It's un-wikipedian only if some content is disputed or you aspire to class B (or C, may vary across wikipedia), or both. I believe you have both. ... | |||

| Maybe some of you folk here can get access to some of those papers in journals where you have to pay a big tax to the publishing company before you can actually read the pdf. That would be useful. | |||
| == Probability paradoxes or counter-intuitive problems == | |||
| Looks like the ] is equally much a mess. | |||
| I published an article in ''Chance'' ( https://www.tandfonline.com/eprint/N2ZHDVNZTCGQBQWTN5ZQ/full?target=10.1080/09332480.2024.2415844) citing flawed reasoning in these types of problems: they ask for the probability of an outome of an event that has occurred but answer with the probability of that outcome before the event has occurred. I edited ] with the correct answer. But since the correct answer contradicts a history of the classical answer, my editing violates the ]. How do I address that (if possible0 to correct what's currently in Misplaced Pages? | |||

| The latest contributions to the Talk page for ] are mostly by me. And two of the sections on the page itself were hurriedly and entirely written purely as uncited "own research" by me. , . | |||
| Well: I think I report the accepted wisdom / folklore in my community. What does the community think? Does the community know good references? ] (]) 14:50, 3 May 2011 (UTC) | |||
| :-The facts are telling: there is so much "accepted wisdom / folklore" and reference to reliable sources is challenging or impossible (and not primarily because some journal content is tax-sheltered, so to speak). Previously I have noted WP troubles handling pedagogy and illustration. Others have said the same regarding exposition (partly in and about Monty Hall arbitration). It is inevitable that distinction between original research and original pedagogy, original illustration, or original exposition is contentious. Yet we may all agree that Misplaced Pages should include entries such as "Monty Hall problem" rather than "'The Monty Hall Problem' in print". | |||
| :-It's possible that the way is clear to writing "Bertrand's paradox" or "Newcomb's paradox" well and without much dispute. If so, I guess it's because there is a ''locus classicus'' in the writings of J.Bertrand or S.Newcomb, not only penned but also discussed in print before any WP editor was born. | |||
| :-Consider the long "See also" sections of some articles on puzzles (problems, paradoxes, etc). No doubt this cornucopia has been generated partly by some teachers and columnists tweaking the corpus. Some have presented wholly new scenarios, with or without coining new titles, while others have presented their own revised versions for their own purposes yet under the old names. Now after a few generations of mass higher education, we have many editors who cut their own eye teeth on one puzzle or another. Indeed, we may have thousands who cut their eye teeth as economics, probability, statistics, logic, or philosophy students, along with hundreds for whom it was their eye teeth as teaching assistants or faculty members. | |||
| :-I think we may agree that it can be good pedagogy to adapt one of these puzzles to a local purpose --specific to the study session, the course of lectures, or the article for in a teaching journal (if not for wikipedia beyond Start class). Except in the teaching journal it may be good practice to do so either with or without changing the scenario (goats for asses; envelopes for wallets) and with various attitudes toward previous authors (credit Bertrand by calling the puzzle Bertrand's, nod to the revisions by not naming him). | |||
| :-Collectively we have learned to think in terms of different versions of these different puzzles and their solutions. For some of us and some of the puzzles, that happened before anyone wrote any version into the literature. | |||
| :-Today I don't have any optimistic or encouraging suggestion. Evidently I have some ideas for an Essay but I admit that I don't yet see it taking any particular shape. I'm not optimistic about that either.--] (]) 17:57, 3 May 2011 (UTC) | |||

| == Notation == | |||
| Several other contributors have mentioned the inconsistency of notation for transposes. Sometimes we have ', sometimes $^T$. At one point (affine transformations) we have a 'dot product' for the same thing. Could we please have consistency? I personally like $^{\rm T}}$, followed by $^T$. Econometricians like ' as T tends for them to indicate time. <span style="font-size: smaller;" class="autosigned">— Preceding ] comment added by ] (]) 09:50, 13 July 2011 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot--> | |||
| : It's a fact of life that different *sources* use different notation. Sooner or later the reader is going to be confronted with this. Now if there is a small group of wikipedia articles on closely related topics that refer to one another a great deal, and which rely on much the same collection of sources, then uniformity of notation within this group would be sensible and an individual editor can seek consensus among the editors of those articles for a preferred notation. But in general I doubt we would ever agree on a preferred notation nor be able to enforce it; and anyway there will be readers coming to statistics articles from physics or from pure mathematics or whereever, who will have to be told specifically "where ... denotes transpose". ] (]) 16:54, 20 July 2011 (UTC) | |||
| ::I am a big fan of notational consistency and I would like to see it across ''large'' rather than small groups of related articles and across ''wide'' rather than narrow reference. For example, all of the articles on named probability distributions might use plain, bold, and italic fonts consistently; lower and uppercase letters; Roman and Greek alphabets; a or k as an integer parameter, or not. For example of wide reference, articles that use particular Poisson distribution(s) should (try to) use the same notation as does ]—same use of 'k' and lambda, for instance. The only question should be how hard to 'try'. --] (]) 22:58, 20 July 2011 (UTC) | |||
| :::May be, but a major question arises in respect to sources ... and after all a major tenet of Misplaced Pages is provision of adequate reference to sources ... it may be best in some cases to match notation to a specific sources reference, so that things can be easily checked. Of course this is only really relevent where there are several parameters where things like m, n, M ,N are switched round in external sources. And, as for example ] suggests that it it not good to use other Misplaced Pages articles as sources, it may in some cases be best to restate things like the pmf of the Poisson distribution (in a local notation if necessary) rather than relying entirely on cross-refs to other articles. ] (]) 08:50, 21 July 2011 (UTC) | |||
| ::: I certainly do support notational consistency when there are a lot of articles referring to one another a great deal. People who feel this is important should try on a few important cases while the lazy or indifferent watch to see how it is received by other editors. ] (]) 12:48, 16 August 2011 (UTC) | |||

Which countries/territories should be included
List of countries and dependencies by population - (This article is listed as Mid-importance on the Statistics WikiProject.)
A difference of opinion has arisen on which countries/territories should be ranked on this article. Specifically, whether all countries/territories should be ranked, or only UN member states.
The section is titled "Sovereign states and dependencies by population". From this title, it's unclear whether disputed states / territories (e.g. Taiwan, Kosovo, Palestine) should be included.
The previous version of this article excluded disputed territories in the ranking, but also excluded dependencies (despite the section title). Presumably this decision was made by a previous editor, because dependencies are not UN members, and only UN members were ranked in the previous article version.
Column 1 of the table retains the UN member-only ranking, which was the only ranking shown in the previous version of this article.
My recent edit added column 2 to the table, which ranks all countries/dependencies.
I opted to keep both columns rather than replace, to take a more conservative/inclusive approach. Discussion has been on whether to have only 1 ranking column, and if so, which to rank. One editor reverted the article to UN members-only ranking without discussion, but I have restored both columns and requested further discussion on the talk page.

Probability paradoxes or counter-intuitive problems
I published an article in Chance ( https://www.tandfonline.com/eprint/N2ZHDVNZTCGQBQWTN5ZQ/full?target=10.1080/09332480.2024.2415844) citing flawed reasoning in these types of problems: they ask for the probability of an outome of an event that has occurred but answer with the probability of that outcome before the event has occurred. I edited Bertrand's box paradox - Misplaced Pages with the correct answer. But since the correct answer contradicts a history of the classical answer, my editing violates the Misplaced Pages:Verifiability#Exceptional claims require exceptional sourcing. How do I address that (if possible0 to correct what's currently in Misplaced Pages?
