详细信息----------Details----------
For the formulas and other details see paretoIV.
对于公式和其他细节,请参见paretoIV。
值----------Value----------
Functions beginning with the letter d give the density, functions beginning with the letter p give the distribution function, functions beginning with the letter q give the quantile function, and functions beginning with the letter r generates random deviates.
功能字母开头的d的密度,以字母开头的函数p的分布函数,函数字母开头的q位数的功能,并以字母开头的函数r随机产生的偏离。
注意----------Note----------
The functions [dpqr]paretoI are the same as [dpqr]pareto1 except for a slight change in notation: s=k and b=alpha; see Pareto.
功能[dpqr]paretoI一样[dpqr]pareto1(略有变化符号:s=k和b=alpha除外);看到Pareto。
