MULTI-SAMPLE SCALE TESTS FOR COMPARING SCALE PARAMETERS WITH EQUAL AND UNEQUAL LOCATION DIFFERENCES

Abstract: In this paper we have discussed some tests which is used for equality of scale parameters under equal and unequal location parameters. Test considered here are Levene's test, Bartlett's test, Box - Anderson Test, Janckknife test, test based on bootstrap and Lepage test. We have found out some results to know the performance (in terms of level and power) of these tests using simulation technique. Results are display in various table and graphs. Discussions and conclusions are made on the basis of results obtained.
