Abstract

We develop an user-interface package mTEXO in the Maplet application for testing exponential upper and/or lower outliers. The distributions of some well-known test statistics for exponential outliers in the literature can be easily evaluated using mTEXO, saving considerable computational time performing numerical integrations and combinatorial algebra necessary in the traditional approach.
