Function name:
T.INV.2T

Category:
Statistical Analysis

Summary:
Calculates the two-tailed inverse of the Student's t-distribution. It finds the value of a random variable for which the two-tailed test value for the Student's t-distribution would be equal to a particular probability.

Syntax:
T.INV.2T(Number; DegreesFreedom)

Returns:
Returns a positive real number which is the inverse of the specified two-tailed test value for the given Student’s t-distribution.

Arguments:
Number is a real number between 0(exclusive) to 1(exclusive) or a reference to a cell containing that number which is the two-tailed test value for which the inverse is to be calculated.

DegreesFreedom is a positive integer value or a reference to a cell containing that value which is the number of degrees of freedom for the Student's t-distribution.


 * If Number is less than or equal to 0 or greater than or equal to 1 then the function returns an error value.
 * If DegreesFreedom is less than 1 then the function returns an error value.
 * If DegreesFreedom is a non-integer value then the function uses its floor value, i.e. it is truncated to an integer.

Additional details:

 * It is such that if T.DIST.2T(x;df) = p or TDIST(x, df, 2) =p then T.INV.2T(p;df) = x.
