Summary Method for MCD objects
MCD对象的方法摘要
译者:生物统计家园网 机器人LoveR
描述----------Description----------
summary method for class "mcd".
summary方法类"mcd"。
用法----------Usage----------
## S3 method for class 'mcd'
summary(object, ...)
## S3 method for class 'summary.mcd'
print(x, digits = max(3, getOption("digits") - 3),
print.gap = 2, ...)
参数----------Arguments----------
参数:object,x
an object of class "mcd" (or "summary.mcd"); usually, a result of a call to covMcd.
类的一个对象"mcd"("summary.mcd");通常情况下,调用covMcd的结果。
参数:digits
the number of significant digits to use when printing.
打印时所使用的数量显著数字。
参数:print.gap
number of horizontal spaces between numbers; see also print.default.
数字之间的水平空间,还见print.default。
参数:...
further arguments passed to or from other methods.
进一步的参数传递给其他方法。
Details
详细信息----------Details----------
summary.mcd(), the S3 method, simply returns an (S3) object of class "summary.mcd" for which there's a print method:
summary.mcd(),S3方法,简单地返回一个对象(S3)的class "summary.mcd"有一个print方法:
print.summary.mcd prints summary statistics for the weighted covariance matrix and location estimates with weights based on MCD estimates. While the function print.mcd prints only the robust estimates of the location and the covariance matrix, print.summary.mcd will print also the correlation matrix (if requested in the call to covMcd with cor=TRUE), the eigenvalues of the covariance or the correlation matrix and the robust (“Mahalanobis”) distances.
print.summary.mcd打印汇总统计数据的加权协方差矩阵和位置估计与基于MCD估计的重量。虽然打印的功能print.mcd只有强有力的位置和协方差矩阵的估计,print.summary.mcd打印也的相关系数矩阵(如果在调用covMcdcor=TRUE的要求的),协方差或相关矩阵的特征值和鲁棒(“马氏”)的距离。
值----------Value----------
summary.mcd returns an summary.mcd object, whereas the print methods returns its first argument via invisible, as all print methods do.
summary.mcd返回summary.mcd对象,而print方法返回其第一个参数通过invisible,作为所有print的方法做。
