ssPilot: Sample Size Calculation for External Pilot Studies for a Continuous Endpoint
An implementation of sample size calculations for external pilot studies that minimize the overall trial sample size for the external pilot and main trial for a continuous endpoint as described in Whitehead et al. (2016) <doi:10.1177/0962280215588241>.
