``` |

`x` |
a sample of effectiveness scores. |

`xmin` |
lowest value to cap scores. |

`xmax` |
highest value to cap scores. |

`qfun` |
a quantile function. |

`abs.tol` |
absolute accuracy requested, passed to |

`subdivisions` |
the maximum number of subintervals, passed to |

`mu` |
the expected value of the distribution (see |

`dfun` |
a density function. |

`pfun` |
a distribution function. |

`...` |
additional arguments passed to other functions, if any. |

`cap`

caps (censor) a variable from below and above.

`effContMean`

computes the expected value of a distribution by numerical integration of the
given quantile function.

`effContVar`

computes the variance of a distribution by numerical integration of the given
quantile function.

`effContTrun`

computes the density, distribution and quantile functions of the distribution
resulting from truncating a given distribution between 0 and 1.

`cap`

: the original vector, but censored.

`effContMean`

: the estimate of the expected value.

`effContVar`

: the estimate of the variance.

`effContTrunc`

: a list with components:

`td` | the truncated density function. |

`tp` | the truncated distribution function. |

`tq` | the truncated quantile function. |
