%description
Tools for blinded sample size re-estimation (BSSR) in two-arm clinical
trials with binary endpoints, together with the exact power and sample
size calculations that the re-estimation relies on. Five exact statistical
tests are implemented: Pearson chi-squared, Fisher exact, Fisher mid-p,
Z-pooled exact unconditional, and Boschloo exact unconditional. Each test
is available with a one-sided or a two-sided alternative, and the exact
unconditional tests can be combined with the Berger-Boos procedure. Sample
sizes can be re-estimated either at the planning stage, to study the
operating characteristics of a design, or from the blinded data of a trial
that is under way. Statistical methods based on Mehrotra et al. (2003)
