:Hello! ALong with your addition to my talk page I have taken a look at some of your edits. I would like to direct you to the teahouse to actually ask a question about what to add to the article and what not to add to articles (most of which can be found in the [[WP:MOS|Manual of Style]]). I have reverted your edits however please note that I do see your edits as being in good faith considering you contacted me first saying that you are a new user wanting to learn. Otherwise, I probably would've given you warnings. [[User:Blaze The Wolf|Blaze The Wolf | Proud Furry and Wikipedia Editor]] ([[User talk:Blaze The Wolf#top|talk]]) 18:17, 2 July 2021 (UTC)
:{{re|Stobene45}} this is mostly a matter of Wikipedia's accepted style conventions. We don't artificially underline subheadings, but rather use the pre-defined styles generated by the staggered classes of headings; and while italics can be used for emphasis, this should be done very sparingly (see [[Wikipedia:Manual_of_Style/Text_formatting#Emphasis]]). As for the citations, references to Google results are not suitable anywhere on Wikipedia - the cited source must be the specific work used, not just a search result containing the work's title.

== Mild error in Examples section ==
In the paragraph beginning "Suppose is [[Normal distribution|normal distributed]]. Then the CDF of is given by" there is an error. The dummy variable "x" is used as the function argument F(x) rather than the upper limit of integration, "t". I will edit to make this F(t).

:@[[User:Joe Gatt|Joe Gatt]] This edit and thread was created by me, I just hadn't logged in. Your edit was incorrect. I think you were confused by the notation - it's OK to have F(x) = int ^ x. What wouldn't be OK would be to have F(X) = int ^ X as a CDF definition (see [[Probability integral transform]]). Technically, X is a function of a probability space. Under certain restrictions, X(w) = x where w is in some original psp and x is in the support or range of the function X.
:As written, the CDF definition is back to being correct. [[User:Chjacamp|Chjacamp]] ([[User talk:Chjacamp|talk]]) 00:20, 24 November 2024 (UTC)
== Please clarify how area inequalities follow from diagram ==
The "Properties" section states the inequalities <math display="block">
x (1-F_X(x)) \leq \int_x^{\infty} t\,dF_X(t)
</math>
and
<math display="block">
x F_X(-x) \leq \int_{-\infty}^{-x} (-t)\,dF_X(t)
</math>
for a random variable <math>X</math> with a finite <math>L_1</math>-norm. These inequalities are straightforward to derive from the formula for the expected value of <math>X</math> using integration by parts. But the article claims that we can instead see why the inequalities are true from the included diagram by "consider[ing] the areas of the two red rectangles and their extensions to the right or left up to the graph of <math>F_X</math>". I don't see how these equalities follow from the diagram; please clarify. [[User:Ted.tem.parker|Ted.tem.parker]] ([[User talk:Ted.tem.parker|talk]]) 00:06, 24 March 2025 (UTC)
== Hatnote to pdf ==
There is [[Talk:Cumulative density function#RfC on redirect, disambig, article, or deletion|a discussion]] (RfC) on what to do with the page [[cumulative density function]]. One option is that it should redirect to this page. Some editors suggest that there should then be a hatnote here linking to [[probability density function]]. Please join the discussion! —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 16:59, 1 May 2025 (UTC)
