Ansari-Bradley test is used for testing the null that s equals
1, the two-sided alternative being that s != 1 (the
distributions differ only in variance), and the one-sided alternatives
being s 1 (the distribution underlying x has a larger
variance, “greater”) or s 1 (“less”). .

the data contain NAs. )To compare results of the Ansari-Bradley test to those of the F test
to compare two variances (under the assumption of normality), observe
that s is the ratio of scales and hence s^2 is the ratio
of variances (provided they exist), whereas for the F test the ratio
of variances itself is the parameter of interest. Suppose that x and y are independent samples from
distributions with densities f((t-m)/s)/s and f(t-m),
respectively, where m is an unknown nuisance parameter and
s, the ratio of scales, is the parameter of interest. test and bartlett.
