resdiuals of random model estimated by plm function
Hi all,
I have estimated a random panel model using plm function.
I have a question about the vector of resduals obtained with the
object $residuals.
example:
data("Produc", package = "plm")
zz <- plm(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp,
model="random", data = Produc, index = c("state","year"))
res<-zz$residuals #

Interaction term in anova - how it should be written in a manuscript table?
Dear Rgurus,
Interaction terms in the linear models function lm are specified by the
colon :
eg: x ~ a + b + a:b
a shortcut for the above is:
x ~ a*b
the output if calling anova on the lm object will be the same in both cases
a ....
b ....
a:b ...
Resdiuals ...
What I am wondering is how the interaction term (a:b) given above should
be written in a table in an manuscript?
a ) a*b
b ) a$\cdot$ b
c ) a:b
d) ....
Cheers Eryk.
