SiegelsEx
(Package: robustbase) :
Siegel's Exact Fit Example Data
A small counterexample data set devised by Andrew Siegel. Six (out of nine) data points lie on the line y = 0 such that some robust regression estimators exhibit the “exact fit” property.

cushny
(Package: robustbase) :
Cushny and Peebles Prolongation of Sleep Data
The original data set was bivariate and recorded for ten subjects the prolongation of sleep caused by two different drugs. These data were used by Student as the first illustration of the paired t-test which only needs the differences of the two measurements. These differences are the values of cushny.

starsCYG
(Package: robustbase) :
Hertzsprung-Russell Diagram Data of Star Cluster CYG OB1
Data for the Hertzsprung-Russell Diagram of the Star Cluster CYG OB1, which contains 47 stars in the direction of Cygnus, from C.Doom. The first variable is the logarithm of the effective temperature at the surface of the star (Te) and the second one is the logarithm of its light intencity (L/L_0).

milk
(Package: robustbase) :
Daudin's Milk Composition Data
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)).
