== 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.
==Thread that also has statistics==
Hello. There is a discussion at [[Wikipedia:Administrators' noticeboard#Many blocks shouldn't be indef]], which has an element of statistics involved. Specifically it relates to calculation of the margin of error. If you are interested in providing input about how margin of error is calculated or the thread in general, you are welcome to join the discussion.

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.
== Consistent notation of the quantile function ==


Would appreciate more input from others as this seems quite an important topic. Please see "Ranking" on the talk page: [[Talk:List of countries and dependencies by population]]. [[User:Snowpeek|Snowpeek]] ([[User talk:Snowpeek|talk]]) 05:22, 24 November 2024 (UTC)
I noticed that different notations are used to denote the [[quantile function]] of probability distributions. The most common ones are <math>Q(p)</math> (e.g. [[Tukey lambda distribution]]), <math>Q(u)</math> (e.g. [[Dagum distribution]]), <math>F^{-1}(\cdot)</math> (e.g. [[Kumaraswamy distribution]]), and <math>x(F)</math> [[Laplace distribution]]. In other cases, the quantile function is redubbed as "random variate generation", and described as a transformation of a standard uniform random variable (rv), i.e. <math>U \mapsto X</math> (e.g. [[Burr Type XII distribution]]).


== Probability paradoxes or counter-intuitive problems ==
Although I realize that this is similarly the case in the literature, I believe that arbitrarily inconsistent notation like this, can be very confusing to readers, especially newcomers. But unlike the published literature, here, the notation can be made consistent.


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#The paradox as stated by Bertrand|Bertrand's box paradox - Wikipedia]] with the correct answer. But since the correct answer contradicts a history of the classical answer, my editing violates the [[Wikipedia:Verifiability#Exceptional claims require exceptional sourcing]]. How do I address that (if possible0 to correct what's currently in Wikipedia?
I don't have a strong preference myself, but I (usually) prefer <math>x(F)</math> over <math>F^{-1}(\cdot)</math> nowadays, since both <math>Q(\cdot)</math> and <math>F^{-1}(\cdot)</math> have no standard for the name of the parameter (I've seen <math>p</math>, <math>q</math>, <math>u</math> and <math>y</math> used in different places).
I can also see that standard uniform transformation notation, e.g. <math>X = -\log(1 - U)</math> for the standard [[exponential distribution]], could be a good choice, but only if it is described as being the "quantile function", and not ''only'' "random variate generation".

:If we were going to try to standardise, I would prefer Q(u), particularly because it leads naturally to q(u) for the density quantile function. But note also that adopting a standard on Wikipedia would make it inconsistent with the way the quantile function is usually presented in the literature for some distributions.

::Coupling the QF notation with that of the QDF makes sense to me.
::I guess that notational inconsistency with the literature is inevitable. I even stumbled accross a <math>G(p)</math> today (C.L. Mallows, '73).
::Perhaps it's a good idea to explicitly list the common QF notations on the [[quantile function]] page? [[User:Jorenham|jorenham]] ([[User talk:Jorenham|talk]]) 02:54, 15 December 2023 (UTC)

Which countries/territories should be included

[edit]

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.

Would appreciate more input from others as this seems quite an important topic. Please see "Ranking" on the talk page: Talk:List of countries and dependencies by population. Snowpeek (talk) 05:22, 24 November 2024 (UTC)[reply]

Probability paradoxes or counter-intuitive problems

[edit]

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.
