Approximating Tail Probabilities of Noncentral Distributions
Abstract
Gray and Wang's (1991) general method for approximating tail probabilities is applied to the cases of noncentral x squared, F and t distributions. The validity of such applications is established. The resulting approximations are easy to compute. Numerical results show the great accuracy of the approximations for all three most commonly used noncentral distributions. (Author) (kr)
