Upper stopping boundaries

For a multi-stage group-sequential design, multiarm requires a choice about the type of upper (efficacy) stopping boundary to use. This can be either fixed (a common interim value), O'Brien Fleming, Pocock, or triangular. Specify your chosen type of upper stopping boundary here. If fixed is chosen, an input box will appear for you to specify the common fixed interim stopping boundary.
