描述----------Description----------
Some observations are harder to classify than others. It is frequently of interest to know which observations are consistenly misclassified; these are candiates for outliers or wrong class labels.
有些意见是比别人更努力,以分类。这是经常的兴趣,知道哪些意见consistenly误判,这些都是为离群candiates或错误类的标签。
参数----------Arguments----------
参数:object
An object of class evaluation, generated with scheme = "observationwise"
一个对象类evaluation以scheme = "observationwise"产生
参数:threshold
threshold value of (observation-wise) performance measure, s. evaluation that has to be exceeded in order to speak of consistent misclassification. If measure = "average probability", then values below threshold are regarded as consistent misclassification. Note that the default values 1 is not sensible in that case
(明智的观察)绩效衡量的阈值。 evaluation有超过发言,一致的误判。如果measure = "average probability",然后值低于threshold一致误判。请注意,默认值1是不理智的在这种情况下
参数:show
Should the information be printed ? Default is TRUE.
应该被打印的信息?默认TRUE。

详情----------Details----------
As not all observation must have been classified at least once,
由于不是所有的观测必须至少有一次被列为
值----------Value----------
A list with two components
两部分组成名单
参数:misclassification
A data.frame containing the indices of consistenly misclassfied observations and the corresponding performance measure.
一个data.frame含有consistenly misclassfied的意见和相应的性能指标指数。
参数:notclassified
The indices of those observations not classfied at all, s. details.
