WorksheetFunction.T_Inv (Excel)

Returns the left-tailed inverse of the Student t-distribution.

If either argument is non-numeric, T_Inv returns the #VALUE! error value. If probability < 0 or if probability > 1, T_Inv returns the #NUM! error value. If deg_freedom is not an integer, it is truncated. If deg_freedom < 1, T_Inv returns the #NUM! error value.

T_Inv (Arg1, Arg2)

Dim dblArg1 As Double: dblArg1 = 
Dim dblArg2 As Double: dblArg2 = 
Dim dblT_Inv As Double
dblT_Inv = WorksheetFunction.T_Inv(Arg1:=dblArg1, Arg2:=dblArg2)

Arguments

Arg1 (Double) - Probability - The probability associated with the Student t-distribution.

Arg2 (Double) - Deg_freedom - The number of degrees of freedom with which to characterize the distribution.
