interval of the proportional treatment effect in a cluster-level
proportional treatment effect model.

`R_t` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the sum of unit-level outcomes in the encouraged cluster of the kth matched pair of two clusters. |

`R_c` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the sum of unit-level outcomes in the control cluster of the kth matched pair of two clusters. |

`d_t` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the sum of unit-level treatment received in the encouraged cluster of the kth matched pair of two clusters. |

`d_c` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the sum of unit-level treatment received in the control cluster of the kth matched pair of two clusters. |

`Z_t` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the encoruagement dose, i.e., the magnitude of the instrumental variable, of the encouraged cluster in the kth matched pair of two clusters. |

`Z_c` |
A length-K vector where K is equal to the number of clusters and the kth entry equal to the encoruagement dose, i.e., the magnitude of the instrumental variable, of the control cluster in the kth matched pair of two clusters. |

`lower, upper` |
The lower and upper endpoints of the interval to be searched. |

`meshsize` |
The meshsize of the grid search. |

`psi` |
A function specifying the score used in the test statistic.
See Details of |

`alpha` |
The level of the confidence interval. |

`double_rank_CI`

constructs a two-sided level-alpha confidence interval
by interting the hypothesis test using a double_rank test. Function
`double_rank_CI`

conducts a grid search with user-specified endpoints
and meshsize in order to construct the confidence interval. For more
details on the double_rank test, see `double_rank`

.

A length-2 vector of two endpoints of the confidence interval.

# Construct a level 0.05 CI for the constant proportional
