A Note on an Extension of Rational Bounds for the t-Tail Area to Arbitrary Degrees of Freedom.
Abstract
Real degrees of freedom arise in the modification of the two-sample t-test when the variances cannot be assumed to be equal. For small degrees of freedom both linear interpolation and standard computer routines may be unsatisfactory. The present paper provides a simple technique for satisfactory estimates of tail probabilities. (Author)
