Description Usage Arguments Details Value

Given a vector of true outcomes and a vector of predictions, returns a list containing performance measures.

1 | ```
myroc(ytest, rit, N = 100)
``` |

`ytest` |
True test outcome: vector of 0s and 1s. |

`rit` |
Predictions for the true outcome. Should be vector of continuous variables between 0 and 1. |

`N` |
Number of breakpoints where we evaluate the performance measures. Default is 100. |

We currently evaluate the performance measures at 100 quantiles of the
predicted values; this can be adjusted via the `N`

option.

A list of performance measures and intermediate computations.

`sens` |
Vector of sensitivity values. |

`spec` |
Vector of specificity values. |

`ppv` |
Vector of PPV values. |

`npv` |
Vector of NPV values |

`area` |
Area under ROC curve (AUC). |

`se` |
Standard error for AUC. |

`cutp` |
Cut points at which the performance measures were computed. |

`cutp.max` |
Cut point which maximizes (sens + spec) / 2. |
