Dear Isobel,
Thanks for the information. Perhaps I didn't explain my request clearly.
What I need is to verify the ideas you suggested in the previous message.
Specifically, (1) Has anybody used the sill values (in geostatistics) to
replace the variances (in classical statistics) in F test? (2)

I see where you are coming from on this, but in fact
the sill is composed of those pairs of samples which
are independent of one another - or, at least, have
reached some background correlation. This is why the
sill makes a better estimate of the variance than the
conventional statistical
Hi Isobel,
Could you explain why it would be a better estimate of the variance when
independance is considered? I'd rather think that we consider the
dependance when the overall variance are to be estimated-- if there
actually is dependance between values.
Or are you talking about modeling sill
Hence my recommendation to use cross cross validation

Sorry to repeat myself - but the samples are not
independent. Independance is a fundamental
assumption of these types of tests - and you
