描述----------Description----------
Calculates the covariance matrix of the normally standardized variables obtained from the columns of x
计算获得从x列通常标准化变量的协方差矩阵
用法----------Usage----------
covariance(x, data = x, cpf = NULL, mean = 0, sd = 1,
step = NULL, prec = 10^-4,
use = "pairwise.complete.obs", type = 3,
extremes = TRUE, sample = NULL, origin_x = NULL,
origin_data = origin_x)
参数----------Arguments----------
参数：x
value to be converted
要被转换的值
参数：data
a sample of data on which a non-parametric probility distribution is estimated
估计的非参数的最后从分布的数据样本
参数：cpf
cumulative probability distribution. If NULL (default) is calaculated as ecdf(data)
累积概率分布。如果NULL（默认）calaculated作为ecdf(data)的
参数：mean
mean (expected value) of the normalized random variable. Default is 0.
平均（预期值）的归一化的随机变量。默认为0。
参数：sd
standard deviation of the normalized random variable. Default is 1.
的归一化的随机变量的标准偏差。默认值是1。
参数：step
vector of values in which step discontinuities of the cumulative probability function occur. Default is NULL
矢量发生在该步骤的累积概率函数的不连续的值。默认是NULL
参数：prec
amplitude of the neighbourhood of the step discontinuities where cumulative probability function is treated as non continuous.
振幅的累积概率函数被视为非连续的步骤的不连续性的附近。
参数：type
see quantile
看到quantile
参数：extremes
logical variable. If TRUE (default) the probability or frequency is multiplied by <p align="center">\frac{N}{N+1}
逻辑变量。如果TRUE（默认值）的概率或频率乘以：<p ALIGN="CENTER">\frac{N}{N+1}
where N is the length of data
在那里N的长度data的
参数：sample
information about sample or probability distribution. Default is NULL
样品或概率分布的信息。默认是NULL
参数：origin_x
date corresponding to the first row of x
迄今为止x的第一行对应于
参数：origin_data
date corresponding to the first row of data
迄今为止data的第一行对应于
参数：use
see cov
看到cov
值----------Value----------
a matrix with the normalized variable or its inverse
一个矩阵，其中的归一化的变量或它的反
注意----------Note----------
It applies normalizeGaussian_severalstations to x and data and then calculates the covariances among the column. See the R code for further details
它适用于normalizeGaussian_severalstations到x和data“，然后计算列之间的协方差。 R代码的进一步详情请参阅
