A data frame with 32 observations on the following 6 variables:
U
U concentration (ppm)
errU
error on the measurement of U concentration
Th
Th concentration (ppm)
ErrTh
error on the measurement of Th concentration
Pb
Pb concentration (ppm)
ErrPb
error on the measurement of Pb concentration
The first 8 observations are group control data (more precisely, they correspond
to standard reference analyses). When testing if all the observations are issued
from a single population, the assumption is thus rejected. Removing the first 8
observations leads to obtain a positive answer when testing if the observations
come from the same population. See demo(srilanka)
