Image[edit]
The image provided could use labels denoting where a and b are located on the x axis and a little more on the meaning of A. How is A defined?RRphys 14:35, 28 September 2007 (UTC)
- I've replaced the old image with a new SVG one for easier editing. I've added labels on the y-axis, but I'm also not entirely sure where a and b labels should go, so I left those out for now. If anyone lets me know I can add them to the diagram easily. --Qef (talk) 00:46, 2 July 2008 (UTC)
- a is the x-axis label for the left-most part of the function when the function when it equals the value A. b is the x-axis label for the right-most part of the function when it equals A. That is,
![{\displaystyle a=\arg \min _{x\in [a,b]}f(x)\,}](https://wikimedia.org/api/rest_v1/media/math/render/svg/5a02bbbcb895533b8e6a6665c25d714c7572c2da)
![{\displaystyle b=\arg \max _{x\in [a,b]}f(x)\,.}](https://wikimedia.org/api/rest_v1/media/math/render/svg/21e20e8b03068ba082cea5a954327670316da48f)

Mentioning the uniform distribution is misleading[edit]
The boxcar function is a function, not a probability distribution. It cannot be expressed "in terms of the uniform distribution" as the article says. Maybe it can be expressed in terms of the probability density function (pdf) of a uniformly distributed random variable. Even better would be to just give the formula and say that the pdf of a uniform random variable is a boxcar function. — Preceding unsigned comment added by 129.187.109.117 (talk) 15:05, 15 December 2020 (UTC)
