WEIBULL3 | R Documentation |

Density, distribution function, quantile function and random generation for the 3-parameter Weibull distribution with shape, scale, and threshold (or shift) parameters equal to `shape`

, `scale`

, and `thres`

, respectively.

dweibull3(x,shape,scale=1,thres=0,log=FALSE) pweibull3(q,shape,scale=1,thres=0,lower.tail=TRUE,log.p=FALSE) qweibull3(p,shape,scale=1,thres=0,lower.tail=TRUE,log.p=FALSE) rweibull3(n,shape,scale=1,thres=0)

`x,q` |
vector of quantiles. |

`p` |
vector of probabilities. |

`n` |
number of observations. |

`shape` |
shape parameter. |

`scale` |
scale parameter. |

`thres` |
threshold (or shift) parameter. |

`log,log.p` |
logical; if TRUE, probabilities p are given as log(p). |

`lower.tail` |
logical; if TRUE (default), probabilities are |

If *Y* is a random variable distributed according to a Weibull distribution (with shape and scale parameters), then *X = Y+m* has a
3-parameter Weibull distribution with shape and scale parameters corresponding to the shape and scale parameteres of *Y*, respectively; and threshold parameter *m*.

`dweibull3`

gives the density, `pweibull3`

gives the distribution function, `qweibull3`

gives the quantile function, and `rweibull3`

generates random deviates.
