### Arguments

`object` |
an object of class |

`theta` |
probability of a positive response |

### Value

A list with the following elements

`B` |
the |

`Nupper` |
vector of N values for stopping on upper boundary |

`dStopUpper` |
vector of probabilities for stopping at each value of Nupper |

`pStopUpper` |
vector of cumulative probabilities for stopping by each value of Nupper |

`Nlower` |
vector of N values for stopping on lower boundary |

`dStopLower` |
vector of probabilities for stopping at each value of NLower |

`pStopLower` |
vector of cumulative probabilities for stopping by each value of NLower |

`Nend` |
N value at the end of the boundary, i.e., max(N) |

`dStopEnd` |
probability of stopping at the end of the boundary |

`check` |
check value, should be 1 or very close to it |
