Arg1 As Double, _
Arg2 As Double _
) As Double
'Usage

Arg2)
double ChiSq_Inv_RT(
double Arg1,

Parameters
Arg1
Type: System.DoubleA probability associated with the chi-squared distribution.
Arg2
Type: System.DoubleThe number of degrees of freedom.
Return Value
Type: System.Double
Remarks
If probability = ChiSq_Dist_RT(x,...), then ChiSq_Inv_RT(probability,...) = x. Use this function to compare observed results with expected ones in order to decide whether your original hypothesis is valid.
If either argument is nonnumeric, ChiSq_Inv_RT generates an error.
If probability < 0 or probability > 1, ChiSq_Inv_RT generates an error.
If degrees_freedom is not an integer, it is truncated.
If degrees_freedom < 1 or degrees_freedom ≥ 10^10, ChiSq_Inv_RT generates an error.
Given a value for probability, ChiSq_Inv_RT seeks that value x such that ChiSq_Dist_RT(x, degrees_freedom) = probability. Thus, precision of ChiSq_Inv_RT depends on precision of ChiSq_Dist_RT(Double, Double). ChiSq_Inv_RT uses an iterative search technique. If the search has not converged after 64 iterations, the function generates an error.
