Compute extrema-weighted features based on functions, predefined local features, and weighting functions

1 2 3 4 |

`xx` |
List of function for which to compute the XWFs |

`t` |
Matrix containing the times at which the functions xx were measured: Element (i,j) contains the time of the j-th measurement of the i-th function. |

`n.i` |
Vector containing the number of measurements for each function. The first n.i[i] elements of the i-th row of t should not be NA. |

`psi` |
Predefined local feature which is a function of a function (first argument) and a measurement time (second argument) |

`w` |
Weighting function. The default is the one used in the original paper. |

`b` |
Parameter of the weighting function. See original paper for details. Ignored if weighting function w is not the default. |

`F` |
CDF of the values of the functions xx. Ignored if weighting function w is not the default. |

`t.min` |
Vector with time of first measurement for each function. Computed from t if omitted but providing it saves computational cost. |

`t.max` |
Analogous to t.min but now the time of the last measurement. |

`t.range` |
Vector with differences between t.max and t.min. Can be supplied to avoid recomputation. |

`rel.shift` |
Optional relative reduction of the integration range to avoid instabilities at the end of the integration ranges. Set to 0 if no such correction is desired. |

`left` |
Boolean specifying whether the left (TRUE) or right (FALSE) extrema-weighted features should be computed: Left and right refer to the weighting function. Ignored if weighting function w is not the default. |

Vector containing the extrema-weighted features obtained by numerical integration for each of the functions.
