gsearly: Creates Group Sequential Trial Designs when Early Outcomes are
Available
Methods to construct and power group sequential clinical trial
designs for outcomes at multiple times. Outcomes at earlier times provide
information on the final (primary) outcome. A range of recruitment and
correlation models are available as are methods to simulate data in order to
explore design operating characteristics. For more details see Parsons (2024)
