Zero-Altered Negative Binomial Distribution
改变零负二项分布
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Density, distribution function, quantile function and random generation for the zero-altered negative binomial distribution with parameter pobs0.
密度，分布函数，位数的函数和参数pobs0零改变负二项分布随机生成。
用法----------Usage----------
dzanegbin(x, size, prob = NULL, munb = NULL, pobs0 = 0, log = FALSE)
pzanegbin(q, size, prob = NULL, munb = NULL, pobs0 = 0)
qzanegbin(p, size, prob = NULL, munb = NULL, pobs0 = 0)
rzanegbin(n, size, prob = NULL, munb = NULL, pobs0 = 0)
参数----------Arguments----------
参数：x, q
vector of quantiles.
向量的位数。
参数：p
vector of probabilities.
向量的概率。
参数：n
number of observations. If length(n) > 1 then the length is taken to be the number required.
若干意见。如果length(n) > 1的长度是所需的数量。
参数：size, prob, munb, log
Parameters from the ordinary negative binomial distribution (see dnbinom). Some arguments have been renamed slightly.
从普通的负二项分布的参数（见dnbinom“）。稍微有些参数已被重命名。
参数：pobs0
Probability of zero, called pobs0. The default value of pobs0 = 0 corresponds to the response having a positive negative binomial distribution.
概率为零，称为pobs0的。 pobs0 = 0对应的默认值具有积极的负二项分布的响应。
Details
详细信息----------Details----------
The probability function of Y is 0 with probability pobs0, else a positive negative binomial(munb, size) distribution.
Y的概率函数0pobs0，其他的正负的二项式（munb，大小）分布的概率。
值----------Value----------
dzanegbin gives the density and pzanegbin gives the distribution function, qzanegbin gives the quantile function, and rzanegbin generates random deviates.
dzanegbin给出了密度和pzanegbin给出了分布函数，qzanegbin给出了分位数的功能，和rzanegbin随机产生的偏离。
注意----------Note----------
The argument pobs0 is recycled to the required length, and must have values which lie in the interval [0,1].
的参数pobs0被回收到所需的长度，而且必须有趴在区间[0,1]值。
