Description Usage Arguments Details Value See Also Examples
Determines possible confidence intervals at the end of a gehan
single-arm trial for a single binary endpoint, as determined
using des_gehan()
. Support is available to compute confidence
intervals a naive ("naive"
) approach only.

A vector of response probabilities to evaluate the expected
performance of the point estimation procedure at. This will internally
default to be the π0

summary |
A logical variable indicating whether a summary of the function's progress should be printed to the console. |
In addition, the performance of the chosen confidence interval determination procedures (including their coverage and expected length) for each value of pi) in the supplied vector pi), will also be evaluated.
Calculations are performed conditional on the trial stopping in one of the
stages specified using the input (vector) k

A tibble in the slot $ci
summarising the possible confidence
intervals at the end of the trial for the supplied design, according to the
chosen methods.
