%description
Software of 'esDesign' is developed to implement the adaptive enrichment
designs with sample size re-estimation presented in Lin et al. (2021)
<doi: 10.1016/j.cct.2020.106216>. In details, three-proposed trial designs
are provided, including the AED1-SSR (or ES1-SSR), AED2-SSR (or ES2-SSR)
and AED3-SSR (or ES3-SSR). In addition, this package also contains several
widely used adaptive designs, such as the Marker Sequential Test (MaST)
design proposed Freidlin et al. (2014) <doi:10.1177/1740774513503739>, the
adaptive enrichment designs without early stopping (AED or ES), the sample
size re-estimation procedure (SSR) based on the conditional power proposed
by Proschan and Hunsberger (1995), and some useful functions. In details,
we can calculate the futility and/or efficacy stopping boundaries, the
sample size required, calibrate the value of the threshold of the
difference between subgroup-specific test statistics, conduct the
simulation studies in AED, SSR, AED1-SSR, AED2-SSR and AED3-SSR.
