It is named after French mathematician … WebThe derivation given by Tim relates more closely to the linear regression derivation, where the amount of error is represented by a Normal distribution when errors are assumed symmetric about a mean, and to decrease away from the mean. I used Tim's answer and made it a little more formal.

WebThe t-distribution, with n degrees of freedom, is given by the equation: f(t) = [ ((n + 1)/2) (1 + x ^2 / n) ^(-n/2 - 1/2)] / [ (n/2) (PI n) ] (See also Gamma Function.)
