David,
A few questions,
How would you determine the number of samples? When you say sampling problem, do you mean
problems in the laboratory?
btw Michel David's example of the use of sichel
t-estimator is the use of five samples from Harmony
Mine. He also goes onto discuss pro's and con's
of having 5 samples
i.e.
arithmetic mean of 5 samples 1195 in-dwt (47.2 gram.metres)
sichel mean of 5 samples
894 in-dwt (35.3 gram metres)
mean derived from 5,170 samples 618 in-dwt (24.4 gram metres)
