TINV

Calculates the inverse of the two-tailed TDIST function.

Syntax:

TINV(p; r)

returns the value x, such that TDIST(x; r; 2) is p.
r (degrees of freedom) is an integer >=1.
p (probability) must be >=0 and <=1.


To calculate the inverse of the one-tailed TDIST function, use TINV(p*2; r), which returns the value x, such that TDIST(x; r; 1) is p.

Example:

TINV(0.666; 2)

returns approximately 0.50.
