Daudin's Milk Composition Data
Daudin的牛奶成分数据

描述----------Description----------
Daudin et al.(1988) give 8 readings on the composition of 86 containers of milk. They speak about 85 observations, but this can be explained with the fact that observations 63 and 64 are identical (as noted by Rocke (1996)).
daudin等人（1988）给出的86的牛奶的容器的组合物上的8个读数。他们讲约85观测的，但是，这可以解释观测63和64是相同的（如Rocke（1996）指出的）的事实。
The data set was used for analysing the stability of principal component analysis by the bootstrap method. In the same context, but using high breakdown point robust PCA, these data were analysed by Todorov et al.(1994). Atkinson (1994) used these data for ilustration of the forward search algorithm for identifying of multiple outliers.
该数据集用于主成分分析的引导方法的稳定性分析。在同样的背景，但使用高击穿点鲁棒PCA，托多罗夫等人（1994年）这些数据进行了分析。阿特金森（1994）利用这些数据ilustration向前搜索算法识别多个离群。
