Robustness of Statistical Tests in the Two-Sample Location Problem

A simulation study was performed to compare three statistical tests with respect to their performances in the two‐sample location problem for contaminated normal distributions. The three tests were: the t‐test, the rank‐transformed t‐test, and the Wilcoxon rank‐sum test. The results showed the t‐tes...

Zusammenfassung:	A simulation study was performed to compare three statistical tests with respect to their performances in the two‐sample location problem for contaminated normal distributions. The three tests were: the t‐test, the rank‐transformed t‐test, and the Wilcoxon rank‐sum test. The results showed the t‐test to be inferior to the other two tests.
