Description Usage Arguments Value References Examples

The `AED1_SSR.CP()`

is used to calculate the conditional
power of the Adaptive Enrichment Design (Strategy 1) with sample size
re-estimation procedure

1 | ```
AED1_SSR.CP(c, Z1, N1, N2)
``` |

`c` |
The critical value used at the final analysis |

`Z1` |
The test statistic obtained at the interim analysis |

`N1` |
The sample size used at the first stage |

`N2` |
The sample size used at the second stage |

A list contains

Critical.Value The critical value used at the final analysis

Conditional.Power The value of conditional power given the observed data
