Abstract
umbrella performs O'Brien's (Biometrics, 1984) Umbrella Test (also known as O'Brien's Multiple Endpoints Test). It is used to test whether a continuous response vector differs between groups of subjects and may be used as a non-parametric alternative to Hotelling's T test. It is particularly useful when each dependent variable denotes an outcome in which higher values are better than lower values or vice versa.
