Grubbs test

Provides a statistical test for the detection of data outliers based on: Grubbs, Frank E. 1969. 'Procedures for detecting outlying observations in samples.' Technometrics 11 (1): 1-21.

The test is based on replicates. Therefore, no outliers are detected for dose steps with less than three observations. Sensitivity is defined by the respective alpha value.
