TINV(p,df<,nc>) |
Range: | 0 p < 1 |
Range: | df > 0 |
Details |
The TINV function returns the p^{th} quantile from the Student's t distribution with degrees of freedom df and a noncentrality parameter nc. The probability that an observation from a t distribution is less than or equal to the returned quantile is p.
TINV accepts a noninteger degree of freedom parameter df. If the optional parameter nc is not specified or is 0, the quantile from the central t distribution is returned.
Note: TINV is the inverse of the PROBT function.
