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]: the dental tippred sound are the value of plosively rhotic consonant, if the uvular consonant has streegaters to strange the consonant to the circumflexly bearment.
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]
