Sample sizes for the exact Fisher type test for noninferiority

1 | ```
bi2ste2(eps, alpha, p1, p2, bet, qlambd)
``` |

`eps` |
noninferiority margin to the odds ratio |

`alpha` |
significance level |

`p1` |
success rate in Population 1 |

`p2` |
success rate in Population 2 |

`bet` |
target power value |

`qlambd` |
sample size ratio |

The program computes the smallest sample sizes *m*,*n* satisfying
*m/n = λ* required for ensuring that the power of the randomized UMPU test does not
fall below *β*.

`eps` |
noninferiority margin to the odds ratio |

`alpha` |
significance level |

`p1` |
success rate in Population 1 |

`p2` |
success rate in Population 2 |

`bet` |
target power value |

`qlambd` |
sample size ratio |

`M` |
minimum size of Sample 1 |

`N` |
minimum size of Sample 2 |

`POW` |
power of the randomized UMPU test attained with the computed values of m, n |
