Function to conduct a statistical test with the null hypothesis that there is no difference between the correlation coefficients between list experiment and endorsement experiment data.

1 2 | ```
comp.listEndorse(y.endorse, y.list, treat, n.draws = 10000,
alpha = 0.05, endorse.mean = FALSE, method = "pearson")
``` |

`y.endorse` |
A numerical matrix containing the response data for the endorsement experiment. |

`y.list` |
A numerical vector containing the response data for a list experiment. |

`treat` |
A numerical vector containing the binary treatment status for the experiments. The treatment assignment must be the same for both experiments to compare across experiments. |

`n.draws` |
Number of Monte Carlo draws. |

`alpha` |
Confidence level for the statistical test. |

`endorse.mean` |
A logical value indicating whether the mean endorsement experiment response is taken across questions. |

`method` |
The method for calculating the correlation, either Pearson's rho or Kendall's tau. |

This function allows the user to calculate the correlation between list and endorsement experiment data within the control group and the treatment group, and to conduct a statistical test with the null hypothesis of no difference between the two correlation coefficients.

`comp.listEndorse`

returns a list with four elements: the
correlation statistic (rho or tau) for the treatment group as
`cor.treat`

, the correlation statistic for the control group as
`cor.control`

, the p.value for the statistical test comparing the two
correlation statistics as `p.value`

, and the bootstrapped confidence
interval of the difference as `ci`
