Abstract: nstage is intended to help one specify the design (sample size, duration, overall operating characteristics) of a multi-arm, multi-stage (MAMS) trial utilizing an intermediate outcome (I-outcome) at the intermediate stages and a definitive or primary outcome (D-outcome) at the final stage. See Royston, Barthel, Parmar & Oskooei (2011) for details of the design and some examples, and Barthel, Royston & Parmar (2009) and Bratton, Choodari-Oskooei & Royston (2014) for further explanations of Stata-related aspects and details of algorithms used.
