This paper investigates certain properties of that procedure, such as how to determine its critical region for small sample sizes, and whether or not the procedure is unbiased and robust. An asymptotic comparison is also made between Lehmann's test and the more well-known test due to Bartlett (1937).<\/jats:p>","DOI":"10.1111\/j.2517-6161.1972.tb00901.x","type":"journal-article","created":{"date-parts":[[2018,12,7]],"date-time":"2018-12-07T05:22:29Z","timestamp":1544160149000},"page":"221-234","source":"Crossref","is-referenced-by-count":7,"title":["On Lehmann's Test for Homogeneity of Variances"],"prefix":"10.1093","volume":"34","author":[{"given":"B.
