韦布尔分布，即韦伯分布（Weibull distribution），又称韦氏分布或威布尔分布，是可靠性分析和寿命检验的理论基础。威布尔分布在可靠性工程中被广泛应用，尤其适用于机电类产品的磨损累计失效的分布形式。由于它可以利用概率值很容易地推断出它的分布参数，被广泛应用于各种寿命试验的数据处理。

The Weibull Distribution Description

Density, distribution function, quantile function and random generation for the Weibull distribution with parameters shape and scale.

Usage dweibull(x, shape, scale = 1, log = FALSE) pweibull(q, shape, scale = 1, lower.tail = TRUE, log.p = FALSE) qweibull(p, shape, scale = 1, lower.tail = TRUE, log.p = FALSE) rweibull(n, shape, scale = 1) Arguments x, q

vector of quantiles.

vector of probabilities.

number of observations. If length(n) > 1, the length is taken to be the number required.

shape, scale

shape and scale parameters, the latter defaulting to 1.

log, log.p

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

lower.tail

logical; if TRUE (default), probabilities are P[X ≤ x], otherwise, P[X > x].
