A Mathematica package has been written to analyse data provided by an iri-
The purpose of inteliaboratory experiments is to study
how an analytical method behaves when set up in different laboratories and
run by various operators over a given period of time.
The aims of an in-
teliaboratory study are to compare the performances of the participating
laboratories and to evaluate the variability of results quantitatively.
This package allows the users, on the one hand to follow step-by-step the
procedure suggested by the ISO-norm 5725  and, on the other hand, to
calculate the repeatability and the reproductibility of the experiment with
an iterative method based on robust statistics .
Most inteliaboratory experiments involve p laboratories, each testing a
specimen (level) n times and the procedure is repeated for a number q
