milk: Daudin's Milk Composition Data
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). 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 was analysed by Todorov et.al. (1994).
Atkinson (1994) used these data for ilustration of the forward
search algorithm for identifying of multiple outliers.source
