message: We need some input on the Talk:Uniform distribution (continuous) page. Michael Hardy and I have had a running discussion on the values of the uniform distribution at the transition points. I think we have settled the text aspect of the problem, but the PDF plot is at issue now. Most of the discussion page is devoted to our back and forth, so if people could read the discussion and put in their two cents, I think we can settle this issue. PAR 03:10, 25 Apr 2005 (UTC)

message: I was playing around with a compound Poisson distribution, which is the sum of a number of identically distributed variables Xi. The number of elements in the sum is a Poisson-distributed variable. For every probability distribution, there will be a compound Poisson version. The one I was working on was one in which the Xi are zeta-distributed. My question is - what is the name of this distribution? "Compound Poisson/zeta" or what?. In general, if XXX is the name of a distribution, whats the name of the compound Poisson distribution over XXX? Thanks - PAR 01:15, 7 Jun 2005 (UTC)

message: Many distributions are in the Exponential family and I think including the exponential family form to  would be a nice addition. It is true that even the exponential family page has only one distribution in the exponential family form, but I think this would be a worthwhile endevor for the wikipedia. I'm not sure how the specification of the natural parameter should be handled, another field or in the exponential family form field. Pdbailey 17:02, 24 April 2006 (UTC)

message: One of the box items points to a non-existing page Template:Probability distribution/link.  The template therefore needs repairing. I don't know what was intended here, so could someone who does know please make the necessary correction. DFH 10:40, 31 March 2007 (UTC)
replies: text: I think what is happening here is that this construction splices the entry in the "type" field (i.e., "mass" or "density") into "Probability <blank> function", which is then made into a wikilink.  When there is no type entry or one besides those two (e.g., Cantor distribution), the construction fails to parse to anything linkable.  How to fix it I don't know, but I hope this helps someone who does.  Baccyak4H (Yak!) 20:10, 21 August 2007 (UTC)
replies: text: I've just noticed that the key to this is the #subpages section above (Bit late for DFH I suspect). It should be straightforward to make another subpage e.g. for singular distributions, if someone really wants to. --Qwfp (talk) 11:53, 10 February 2008 (UTC)

message: Whenever one of the fields is done using LaTeX math markup and the result converted to PNG rather than to HTML, the background is white, which clashes with the table background color.  Is it possible to change either the table background or the rendering math background to be consistent or at least less clashing?  
I believe I tried to find a way to change the math background some time ago but never succeeded, so suspect the table would be where it is possible.  Any thoughts or suggestions? Baccyak4H (Yak!) 18:45, 15 April 2008 (UTC)

message: Per a discussion on the math ref desk, I had the idea of allow a field in this template for the probability-generating function for discrete (i.e., type=mass) distributions.  It certainly may be useful, and relevant, but it may make the template a little big and bulky.  Thoughts? Baccyak4H (Yak!) 14:27, 4 September 2008 (UTC)
replies: text: Yes, and the cumulant generating function is also worthwhile considering for the template. Bo Jacoby (talk) 15:07, 4 September 2008 (UTC)
replies: text: It would be worthwile to add these fields, especially since for some distributions the pgf cannot be found anywhere in the article (e. g., Poisson distribution), even if it is—more or less—trivial to compute. --130.92.9.57 (talk) 14:40, 27 February 2009 (UTC)

message: 22-Feb-2009: I am setting the right-hand margin to zero for the infobox, by using the style coding "margin-right: 0em". Formerly, it had shifted the infobox to the left by about 4 letters (characters), causing the left-side text to be squeezed by 4 letters more narrow. This change should cause most articles to allow more text to the left-side of the infobox. -Wikid77 (talk) 15:25, 22 February 2009 (UTC)
thread_title: Narrowing right-side margin for wider text

message: 22-Feb-2009: I am adding new parameter "box_width" (default 325px) to allow narrowing the infobox to allow more left-side text. Also, new paramter "marginleft" sets the left-hand margin outside the infobox, by using the style coding "margin-left: 1em". Formerly, the infobox had always been shifted from the left-side text by about 4 letters (characters), causing the left-side text to be squeezed by 4 letters more narrow. Those changes should not affect any articles, until those new parameters are specified within an article, to allow more text to the left-side of the infobox. -Wikid77 (talk) 15:25, 22 February 2009 (UTC)

message: 22-Feb-2009: I have put a limited amount of documentation inside the template, to be displayed (as typical) during the template stand-alone mode. New versions of the MediaWiki software skip the documentation when formatting pages, and older versions could allow at least 10 copies of a medium-sized template to be used within one article, before the template-processing buffers filled with coding & documentation. The English Wikipedia has been upgraded to skip template-documentation text since January 2008. Documentation text has always been omitted before displaying an article page over the Internet (unless editing the template).
Feel free to revise or reduce that documentation in the template. -Wikid77 (talk) 15:25, 22 February 2009 (UTC)
thread_title: Put some documentation inside template

message: Presently the template uses the notation such as "[0;4]" to indicate an interval from 0 to 4 inclusive. I am not familiar with a semi-colon being used to denote an interval. I have always seen commas used (at least in English textbooks) such that the previous interval would be denoted by "[0,4]". Is the semi-colon in common use in statistics? My experience in analysis is such that I have only come across the comma. Jason Quinn (talk) 19:33, 9 May 2010 (UTC)
replies: text: The template doesn't enforce any particular formatting for the support intervals (and in fact, support is rarely an interval). If you feel the commas are more appropriate, feel free to edit the support value in the infobox.  // stpasha »  19:44, 9 May 2010 (UTC)
replies: text: You are correct that it is not the template itself. I don't know what I was thinking when I wrote that. Still I am curious why ";" has been used very consistently in the support intervals when people have used this template. If it is not common practice, I may end up changing it in the future but I'll wait for more input. Jason Quinn (talk) 20:53, 9 May 2010 (UTC)

thread_title:  Proposal to add corresponding computer functions in common statistical languages; 

message: Hello everyone,
I've been looking to several probability distribution articles on Wikipedia, and I'm surprised to see that the rendering of each probability and cumulative density function is not uniform, which can be unpleasant when you are trying to compare two functions side-by-side.
There's a lot of distribution to cover, in my opinion the most common ones would be:
* beta
* binomial
* Cauchy
* chi-squared
* exponential
* F
* gamma
* geometric
* hypergeometric
* log-normal
* logistic
* negative binomial
* normal
* Poisson
* Student's t
* uniform
* Weibull
I'm not an expert at data visualization, and I have no preference over what style to use, as long as it is consistent across all distributions.
Best regards,

thread_title:  Uniform probability distribution graphs 

message: Hi all! I'm coming from the Normal Distribution Talk Page. I was missing the mean average deviation or as mathematicians call it the first absolute central moment, and was informed to that to add it there, I would have to add it here / to this template first. I argue that as this metric is more frequently used by laypeople than e.g. variance, and I feel the Normal Distribution wikipedia page should connect to laypeople as much as it does to statisticians. I agree also, however that changing a (this) template is no small deal, that's why I'm stopping by here to ask. So:
:1. What do others here think? Should/may I add this field to the template, and fill it out for the normal distribution?
:2. What should we call it? I suggest MAD for short as this abbreviation is used frequently, and direct the link to average absolute deviation.
:3. Can anyone help me on how I do this, or should I figure it out myself?
:4. If 1, I can also go and work out this value for other distributions, and add it there, e.g. Binomial, Poisson, you name it. Does anyone see a specific distribution that I should add it to also, → make a wish ;)
:→ If I hear back from you, all the better, if not, I'll try to figure out #3 myself, implement #1,2, for normal distribution and 4: for binomial distribution.
Cheers & thanks! Michi zh (talk) 20:42, 12 January 2020 (UTC)
replies: text: Done! I didn't add it for the Binomial however, as that formula is quite unwieldy (see http://mathworld.wolfram.com/MeanDeviation.html). Should I delete this section now? Best Michi zh (talk) 22:44, 16 January 2020 (UTC)

message: Hi there,
Why this warning message: "Warning: Page using Template:Infobox probability distribution with unknown parameter "value_at_risk" (this message is shown only in preview)." appears at this page "Log-normal distribution"? And how we can resolve it?
It should be mentioned that this warning is ignored but appears when we are in "Preview" page, and I cannot find the "value_at_risk" parameter in this template to resolve it. Any idea?
Thanks, Hooman Mallahzadeh (talk) 08:33, 15 October 2020 (UTC)
replies: text: Some value-at-risk type measures have been added to this template and then put into all the distribution pages. There's no reason for highly specialized fields like this to show up in the infobox for every distribution -- there are tons of other things that could be included in the infobox. 199.169.204.151 (talk) 21:03, 25 August 2023 (UTC)

message: I tend to add parameters "raw moments" and "central moments", with links to Moment (mathematics).
For instance, the normal distribution has central moments
:E[X^n] = [n\text{ even}]\sigma^n(n-1)!!;
the log-normal distribution has raw moments
:E[X^n] = \exp\left(k\mu+k^2\sigma^2/2\right).

message: Looking at examples of use for Desktop and Mobile, there seem to be two small issues on the mobile version: (1) odd positions of dividers within some rows compared to the other rows and (2) disappearing borders of the final row actually used.  For example in https://en.m.wikipedia.org/wiki/Wrapped_Cauchy_distribution, the PDF box look misaligned while it is not clear whether the final CF row is part of the infobox or a note.  Compare this to https://en.wikipedia.org/wiki/Wrapped_Cauchy_distribution which looks more consistent between rows.
