The GrubbsTest type exposes the following members.
Use the GrubbsTest class to test whether
the value with greatest deviation from the mean in a sample is
The test has two-sided and one-sided versions. In the one-sided
version, the null hypothesis is that the smallest (one-tailed lower)
or largest (one-tailed upper) value in the sample is not an outlier.
In the two-sided version, the null hypothesis is that neither
the smallest or the largest value are outliers.
This test assumes that the sample is drawn from a normal distribution.
It can only test for a single outlier. If you suspect there is more than
one outlier, the GeneralizedEsdTest is the test of choice.
