Resumen de The Null Distribution of the Likelihood-Ratio Test for One or Two Outliers in a Normal Sample.

Jing Zhang, Keming Yu

• For testing k upper or lower outliers in a normal sample, the sampling distribution of the likelihood-ratio statistic is still unknown in the literature except for k=1. In this paper, we find its exact distribution for k=2 and tabulate the extensive critical values, which are compared with the traditional simulated values.
