linear correlation?
...a constant.
As for your second question, the correlation estimator is a continuous
function of each of the individual data points, so perturbing the values of
any of them by a sufficiently small amount will only perturb the correlation
by a small amount.

interpretation of lm
...n we construct in R a
response surface so that we can optimise the levels of
the factors by maxmising the response surface, can you
advise me how to do that in R?
6) if the number of factors is over 1000, is it
possible to analyse the effect of each factor using
the same way as above?
Many thanks
Dechao

Dear R help users:
I have set up a r help mailing list archive based on mysql which support
full text search and auto-update.
