Syntax:
T.INV.2T(Probability, DegreesFreedom)
Description:
Returns the inverse of the two-tailed Student's t-distribution function (i.e., percentiles of this distribution).
Probability is the two-tailed probability to be evaluated. Must be in the range 0 to 1.
DegreesFreedom is the number of degrees of freedom. Must be ≥ 1. Integer numbers are expected. Digits to the right of the decimal point are ignored.
Please note: The result of this function is calculated using an iterative search technique. If PlanMaker does not find a result after 100 iterations that deviates less than ±3x10^-7 from Probability, it displays the error value #N/A and aborts the approximation.
Note:
The T.INV.2T function supplements together with T.INV the previous TINV function.
T.INV.2T returns the same result as TINV (two-tailed percentiles).
T.INV (left-tailed percentiles) is completely new.
Compatibility notes:
Microsoft Excel supports this function only in version 2010 or later. In older versions, the function is unknown.
