Abstract:
|
This paper proposes a modification to the traditional nonparametric Mood's test to carry out hypothesis tests for "quantile-preserving spreads" defined in Mendleson (1988). The test makes use of a procedure for estimating the crossing point of two distributions developed in a master's report by Zong (2004). Critical values for the proposed test are tabulated using Monte Carlo simulation. A simulation study is carried out to compare the proposed test with the classical rank tests developed by Mood, Ansari-Bradley, Seigel-Tukey, and Mendelson as well as a test proposed by Zong (2004). The use of the test is demonstrated using guinea pig data given in Doksum (1974).
