How to add statistics symbols in Excel like y-hat, bar x, etc.

[Tritanic]

Excel is used extensively for statistical work, but does not support specialized statistical characters. For example, the sample mean is usually written as 'x' with a bar over it, or x-bar. The equation to approximate regression is referred to as y-hat, the letter y with a caret (^) on top. I believe inclusion of all of the specialized statistical symbols in the character set would add in the presentation of statistical analysis done in Excel.

This is a font question/suggestion, not an Excel question/suggestion. As such, it more properly belongs in a newsgroup that deals with fonts, such as comp.fonts. With a font editor, you could create a font that has whatever characters that you wish. Googling similar previous previous requests indicates that x-bar is already available in at least 2 fonts:. They are Font MS Reference 1 and Math Ext and check that you might already have. Also a multiple character approach of underscore, followed by new line (alt+enter) then X that could be adapted to y-hat.

I know this is Microsoft Word. You just need to click on Insert > Object and you click in the list of Microsoft equation. If you do not find entrust the installation CD of Microsoft Office in your CD player, and you can choose the option to install / uninstall and looking for Microsoft Equation (normally it is in Microsoft Office Tools) it is very easy to use and it gives you all the special symbols and notations (premiums, bars, dies, braces etc ...). Just check if there is any similar option.
