X̂ is the Latin letter X with a circumflex. The letter is used in the modern orthography of the Aleut language[1] and in the current Alaska Native Language Center alphabet of the Haida language.[2] In both cases, it represents the sound [χ].
In mathematics, x̂ often refers to the unit vector in the +X direction. In statistics, it can also represent the predicted value for x, consistent with the hat notation.[3]
