This function allows to calculate the segments slope that connect the ROC curve segments with the reference point (1,0).

1 | ```
curvesegsloperef(curve.fpr, curve.tpr, ref.point)
``` |

`curve.fpr` |
False positive rate vector with all points of the given Curve |

`curve.tpr` |
True positive rate vector with all points of the given Curve |

`ref.point` |
Reference point where we start drawing the sample lines |

This function returns a vector with all segments slopes that connect the ROC curve points to the reference point.
