描述----------Description----------
A collection of method to validate the goodness of the model. Since there is no well identified global optimization criterion each part of the model needs to be validated.
集合的方法来验证的善良的模型。由于没有确定的全球优化准则每个模型的一部分,需要进行验证。
用法----------Usage----------
rSquared(object, ...)
## S3 method for class 'sempls'
rSquared(object, na.rm=FALSE, ...)
## S3 method for class 'rSquared'
print(x, na.print=".", digits=2, ...)
qSquared(object, ...)
## S3 method for class 'sempls'
qSquared(object, d=NULL, impfun, dlines=TRUE,
total=FALSE, ...)
## S3 method for class 'qSquared'
print(x, na.print=".", digits=2, ...)
dgrho(object, ...)
## S3 method for class 'sempls'
dgrho(object, ...)
## S3 method for class 'dgrho'
print(x, na.print=".", digits=2, ...)
communality(object, ...)
## S3 method for class 'sempls'
communality(object, ...)
## S3 method for class 'communality'
print(x, na.print=".", digits=2, ...)
redundancy(object, ...)
## S3 method for class 'sempls'
redundancy(object, ...)
## S3 method for class 'redundancy'
print(x, na.print=".", digits=2, ...)
rSquared2(object, ...)
## S3 method for class 'sempls'
rSquared2(object, na.rm=FALSE, ...)
## S3 method for class 'rSquared2'
print(x, na.print=".", digits=2, ...)
gof(object, ...)

gof(object, ...)
## S3 method for class 'gof'
print(x, na.print=".", digits=2, ...)
参数----------Arguments----------
参数:object
An object of class sempls.
对象的类sempls。
参数:d
A numeric value for the omission distance. Thus choosing d=N, where N is the number of complete observations, is leaving one out cross validation. This is done when d takes its default value NULL.
Anumeric这个值的遗漏距离。因此选择d=N,其中N是完整的观测,留下一个交叉验证。这是时d把它的默认值NULL。
参数:impfun
An user specified function to impute missing values.
用户指定的功能,以填补缺失值。
参数:dlines
If TRUE the same observations are deleted for a whole block of MVs, else each dth , counting from top left to bottom right, observation is deleted.
如果TRUE相同意见都将被删除的整个块的MV,其他各d日,由左上到右下计,观察被删除。
参数:total
If total=TRUE total effects are used instead of path coefficients to calculate the predictions.
如果total=TRUE总的效果,而不是路径系数计算的预测。
参数:na.rm
If na.rm=TRUE observation with missing values are discarded before analysis.
如果na.rm=TRUE遗漏值的观察与被丢弃在分析前。
参数:x
An object of the according class.
根据类的一个目的。
参数:na.print
A character substituting values not to be printed.
Acharacter值替换不被打印出来。
参数:digits
minimal number of _significant_ digits, see print.default.
数量最少的_significant_数字,请参阅print.default。
参数:...
Arguments to be passed down.
要传递了下来。
值----------Value----------
Most GOF methods return a column vector with the names of the variables as rows and the respective measure as column.
大多数GOF的方法返回与作为行和相应的措施,作为列的变量的名称的列向量。
