Chebycheff's Inequality redivivus!
Tables of the tolerance factors may be found in the following two
venerable texts. (They can also be calculated from the inequality with a
number of numerical analysis packages for the Mac or the PC)

We're doing some research in statistical classification of abnormalities
in retinal images (that is, pattern recognization), and we need to
estimate the size of the sample nescesary. We've heard of some tables
for this purpose and would like to know if someone knows where to
find them

Dear Sir or madam,
Sorry to bother you with a minor "student" problem. I was referred to you
by professor Howell who suggested you may be able to
help me with a statistical problem I have not been able to solve myself so

I'm not sure if this will help the immediate need, but the ASTER program
is the work of blind mathematician's PhD work and can "read" mathematics
(and arithmetic expressions) that have been typeset with the TeX system.

So, it is usually not a good idea to ask to be removed from a spam

The crux of what Mike originally asked is "how good is my measurement
system." My (limited) understanding is that the concept of correlation is
not relevant to this application. Refer to some of the papers on the
calibration problem, such as those by Eberhardt & Mee (there are several

Another note on this: Much of the original Mandel work seems to have been
done using classical linear regression, although the later stuff
incorporated errors-in-variables regressions. There is a recent update on
the use of this technique (with further references) in:
