Checks whether the middle point is located below or on the line connecting its neighbors.

LineCon(f1, f2, f3, fp1, fp2, fp3)
``` |

`f1` |
Goodness-of-fit value for the first point |

`f2` |
Goodness-of-fit value for the second point |

`f3` |
Goodness-of-fit value for the third point |

`fp1` |
Number of effective parameters for the first point |

`fp2` |
Number of effective parameters for the second point |

`fp3` |
Number of effective parameters for the third point |

`ret` |
Value that indicates if the middle point is located below or on the line connecting its neighbors (0 if the middle point is not located below the line connecting its neighbors, 1 if the middle point is not located on the line connecting its neighbors) |
