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)

There is [[Talk:Cumulative distribution 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)
