New approximations to student t-distribution

R. Ramakrishna and Naveen Kumar Boiroju

Some normalizing transformations to t-distributions are discussed in this paper. A normal approximation and a logistic approximation are proposed for the t-distribution function. The accuracy of the proposed approximations is compared with the existing normal approximations to t-distribution. The proposed approximations are very easy to use and promising at least three decimals accuracy
