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. ChiSq_Inv_RT uses an iterative search technique. If the search has not converged after 64 iterations, the function generates an error.
