Arcsine transformation article redirecting into this one is a category error

The major value of an Arcsine transformation article would be to explain why the transformation 2 arcsin(sqrt(Y/n)) (sometimes without the 2) is applied to binomial variables, Y (briefly, to stabilize the binomial variance). People looking for that information will find no useful information here, but multiple stats-related articles do link to the Arcsine transformation page in order that they can find information on it, and they get redirected to this page, which is no help at all - a binomial proportion is nothing like a continuous (standard) uniform, where there would be a connection to this distribution. That widely used transformation of binomial proportions is not directly related to this distribution and the result of doing it is certainly not from the Arcsine distribution. Nothing here now is relavant to it, and there is no place here to even add the information people who get redirected will be looking for; it would not belong in an article on the distribution and if it were to be added, should be removed.

As I replied to at WP:HD, the link you provided doesn't have a history of an article existing. Have you got a target where it might have been? Lee Vilenski ^{(talk • contribs)} 00:08, 3 November 2025 (UTC)[reply]

Thanks for your kind help, you're right. I modified the original comment above to make it reflect the actual situation (that it shouldn't have redicted here) rather than my errorneous interpretation of what I saw; the artice I recall reading must have been one of the subpages relating to it. I am writing a a new page in sandbox to put at Arcsine transformation when it's ready. Glenbarnett (talk) 00:38, 3 November 2025 (UTC)[reply]

Support - open or closed?

@Mgnbar: In relation to this reversion: https://en.wikipedia.org/w/index.php?title=Arcsine_distribution&oldid=1251766937

There are already numerous pages for probability distributions with a non-closed support listed in their article. Those that I have found are: Logit-normal_distribution, Kumaraswamy_distribution, Wrapped_exponential_distribution, Wrapped_Cauchy_distribution, Wrapped_asymmetric_Laplace_distribution, Inverse-chi-squared_distribution, Scaled_inverse_chi-squared_distribution, Dagum_distribution, F-distribution, Fréchet_distribution, Gamma_distribution, Inverse-gamma_distribution, Generalized_gamma_distribution, Hotelling's_T-squared_distribution, Inverse_Gaussian_distribution, Lévy_distribution, Log-Cauchy_distribution, Log-normal_distribution, Nakagami_distribution, Type-2_Gumbel_distribution and Balding–Nichols_model.

Based on this, I propose that my edit of the support being an open interval should re-instated.

Adding to the list Benini_distribution, Burr_distribution, Davis_distribution, Generalized_inverse_Gaussian_distribution, Log-t_distribution, Maxwell–Boltzmann_distribution, ARGUS_distribution and Beta_rectangular_distribution HailSaturn (talk) 12:16, 19 October 2024 (UTC)[reply]

You gather a lot of evidence that suggests you're right. I was going to ask at Wikipedia talk:WikiProject Mathematics, whether there's a policy. But Support (mathematics) suggests that your notion of support is sometimes used in probability. So please go ahead and make your edit. And I apologize for wasting our time. :) Mgnbar (talk) 14:05, 19 October 2024 (UTC)[reply]
