Ansari-Bradley test

returns
a test decision for the null hypothesis that the data in vectors `h`

= ansaribradley(`x`

,`y`

)`x`

and `y`

comes
from the same distribution, using the Ansari-Bradley test. The alternative
hypothesis is that the data in `x`

and `y`

comes
from distributions with the same median and shape but different dispersions
(e.g., variances). The result `h`

is `1`

if
the test rejects the null hypothesis at the 5% significance level,
or `0`

otherwise.

returns
a test decision for the Ansari-Bradley test with additional options
specified by one or more name-value pair arguments. For example, you
can change the significance level, conduct a one-sided test, or use
a normal approximation to calculate the value of the test statistic.`h`

= ansaribradley(`x`

,`y`
