Hello,
Couple of clarifications:
- A,B,C,D are factors and I am also interested in possible interactions but the
model that comes out from aov R~A*B*C*D violates the model assumptions
- My 2^k is unbalanced i.e. missing data and an additional level I also include
in one of the factors i.e. C
-
Giovanni:
1. Please read ?formula and/or An Introduction to R for how to specify
linear models in R.
2. Correct specification of what you want (if I understand correctly) is
log(R) ~ A*B + C + D
3. ... which presumably will also fail because some of your factors
have only one level, which means
Hello Bert,
Thank you for taking the time to try to answer.
1) I know this, however if one is interested in only interaction between two
specific factors then in R one uses I(A*B*C) meaning 3-way anova for that and
not the implicit 2-ways that would otherwise be computed.
2) True, but it

Hello Rob,
Thank you for your suggestions. I tried glm too without success. Anyhow I
include all the information just in case someone with good knowledge can give
me a hand with this. I take log of the response variable because:

- the

This sort of post seems to me to be completely unacceptable.
Is there a mechanism by which the list manager can unsubscribe
Mr. Azua and keep him unsubscribed until he learns some manners?
cheers,
