An Asymptotic Expansion for the Tail Area of the t -Distribution

Abstract By means of elementary methods, an asymptotic expansion with error bounds is obtained for the t-tail area. It is indicated how this result may be used to approximate small t percentiles. A sufficient condition for the ratio of the t-tail area to the normal tail area to approach unity is also given.
