描述----------Description----------
Density function and random generation for the Poisson-Tweedie family of distributions.
密度函数和特威迪家庭的泊松分布的随机生成的。
用法----------Usage----------
dPT(x, mu, D, a, tol = 1e-15)
rPT(n, mu, D, a, max = 10*sqrt(mu*D), tol = 1e-4)
参数----------Arguments----------
参数:x
an object of class 'mlePT' or a non-negative vector containing the integers in which the distribution should be evaluated.
类的“mlePT或一个非负的向量,包含整数中的分布应评估对象。
参数:mu
numeric positive scalar giving the mean of the distribution.
数字正标,给人的平均分布。
参数:D
numeric positive scalar giving the dispersion of the distribution.
数字正标量,分布分散。
参数:a
numeric scalar smaller than 1 giving the shape parameter of the distribution.
数字标量超过1分布的形状参数小。
参数:tol
numeric scalar giving the tolerance.
数字标给予宽容。
参数:n
integer scalar giving number of random values to return.
整数标量随机值返回。
参数:max
numeric scalar containing the maximum number of counts to be used in the sampling process.
数字标包含在采样过程中使用的计数的最大数量。
值----------Value----------
If 'x' is of class 'mlePT', 'dPT' will return the Poisson-Tweedie distribution with parameters equal to the ones estimated by 'mlePoissonTweedie' evaluated on the data that was used to estimate the parameters. If 'x' is a numeric vector, 'dPT' will return the density of the specified Poisson-Tweedie distribution evaluated on 'x'.
如果X是类的mlePT,三联将返回与参数估计mlePoissonTweedie上的数据被用来估计参数评估的泊松特威迪分布。如果x是一个数值向量,三联将返回指定泊松特威迪X评估分布密度。
'rPT' generates random deviates.
“RPT”产生随机的偏离。

举例----------Examples----------
# To compute the density function in 1:100 of the Polya-Aeppli[在1:100的波利亚-Aeppli的密度函数计算]
# distribution with mean = 20 and dispersion = 5[分布均值为= 20和分散= 5]
dPT(x = 1:100, mu = 20, D = 5, a = -1)
# To generate 100 random counts of the same distribution with same[相同的同分布的随机数生成100]
# parameters[参数]
