In order to put a hat on a character that is to be displayed within a figure, the "Interpreter" property of the text should to be set to "LaTeX" and the equivalent LaTeX command "\hat{x}" should be typed as "$$\hat{x}$$".
If you want to write a letter with a tilde on top of the letter, you can write $\tilde{x}$ . In this example the tilde will be displayed above the “x”. If you want more then one letter below the tilde you can use $\widetilde{xyz}$ .
By writing $\hat{\alpha}$ I got alpha hat in text.

In statistics, a circumflex (ˆ), called a "hat", is used to denote an estimator or an estimated value. For example, in the context of errors and residuals, the "hat" over the letter indicates an observable estimate (the residuals) of an unobservable quantity called. (the statistical errors).
A circumflex (ˆ) is a chevron-shaped diacritic glyph in Latin script. In Greek script, the symbol appears in the shape of a tilde (~). The diacritic also appears in mathematics under the monikers "hat," "house," and "roof."
LaTeX Spacial Characters
If you simply want the character to be printed just as any other letter, include a \ in front of the character. For example, \$ will produce $ in your output. The exception to the rule is the \ itself because \\ has its own special meaning. A \ is produced by typing $\backslash$ in your file.
Ñ, or ñ (Spanish: eñe, [ˈeɲe] ( listen)), is a letter of the modern Latin alphabet, formed by placing a tilde (also referred to as a virgulilla in Spanish, in order to differentiate it from other diacritics, which are also called "tildes") on top of an upper- or lower-case N. It became part of the Spanish alphabet in ...
You simply type \LaTeX . One problem with this is that if you type it a lot of times in your text you will need to type \LaTeX\␣ ¹ (i.e., followed by \ and an actual space) to force a space after it. \xspace is from the xspace package. Additionaly, writing \LaTeX{} adds the space after.
In mathematics and statistics, the circumflex diacritic is sometimes used to denote a function and is called a hat operator. A free-standing version of the circumflex symbol, ^, is encoded in ASCII and Unicode and has become known as caret and has acquired special uses, particularly in computing and mathematics.
Â, â (a-circumflex) is a letter of the Inari Sami, Skolt Sami, Romanian, and Vietnamese alphabets. This letter also appears in French, Friulian, Frisian, Portuguese, Turkish, Walloon, and Welsh languages as a variant of the letter "a".
