Estimate the area of region under ROC curve under pre-specific FPR/TPR constraints (two-way partial AUC). See Yang et al., 2016 for details.

`response` |
a factor, numeric or character vector of responses; typically encoded with 0 (negative) and 1 (positive). Only two classes can be used in a ROC curve. If its levels are not 0 and 1, the first level will be defaultly regarded as negative. |

`predictor` |
a numeric vector of the same length than response, containing the predicted value of each observation. An ordered factor is coerced to a numeric. |

`threshold` |
a length-two numeric vector; the first element is FPR threshold, the second is TPR. |

`smooth` |

This function estimates two-way partial AUC given response, predictor and pre-specific FPR/TPR constraints.
