Use T_INV_2T to calculate the inverse of the two-tailed distribution of Student's t-distribution.
Syntax
SELECT [wct].[T_INV_2T](
  <@Probability, float,>
 ,<@Degrees_freedom, float,>)
Arguments
@Probability
the probability to be evaluated. @Probability must be of a type float or of type that intrinsically converts to float
@df
the number of degrees of freedom. @df must of a type float or of a type that intrinsically converts to float.
Return Type
float
Remarks
·         0 < @df
·         0 < @Probability <= 1
·         If @Probability = 1 then zero is returned
Examples
In this example we calculate the value at 0.95 with 12 degrees of freedom.
SELECT
       wct.T_INV_2T(
               0.95 --@Probability
              ,12    --@Degrees_freedom
              ) as T_INV_2T
