Precision Formulae
Please could there be a definition of a “precision” formula, or a link to a definition? JDAWiseman (talk) 14:52, 10 July 2012 (UTC)

Marshall-Edgeworth index
I finally wandered over to this article, and I think that it's a fine contribution! I would like to see the Marshall-Edgeworth index
 * $$P_{ME}=\frac{\sum [p_{c,t_n}\cdot \frac{1}{2}\cdot(q_{c,t_0}+q_{c,t_n})]}{\sum [p_{c,t_0}\cdot \frac{1}{2}\cdot(q_{c,t_0}+q_{c,t_n})]}=\frac{\sum [p_{c,t_n}\cdot (q_{c,t_0}+q_{c,t_n})]}{\sum [p_{c,t_0}\cdot (q_{c,t_0}+q_{c,t_n})]}$$

added to it. —SlamDiego&#8592;T 10:37, 30 June 2008 (UTC)


 * I added the Marshall-Edgeworth formulas plus some other information I found on it. Feel free to add any other formulas. I've been slow to flesh this out.--Bkwillwm (talk) 03:38, 1 July 2008 (UTC)


 * Okay. I just don't want to screw-up any longer-term vision that you have for this article.  I realize that every article is (barring protection) open to edits by anyone in theory, but I've seen some well-conceptualized articles run right off the rails by well-intentioned edits from newcomers. —SlamDiego&#8592;T 04:57, 1 July 2008 (UTC)

Resizeable delimiters
You can get automatically resized parentheses and brackets thus:
 * \left( \right(  \left[  \right]

For example
 * &lt;math&gt;(\frac{1}{2})&lt;\math&gt;

renders as
 * $$(\frac{1}{2})$$

but
 * &lt;math&gt;\left(\frac{1}{2}\right)&lt;\math&gt;

renders as
 * $$\left(\frac{1}{2}\right)$$
