Subject: [R] Weird SEs with effect()
Hi all,
Im a little bit confused concerning the effect() command, effects
package.
I have done several glm models with family=quasipoisson:
model -glm(Y~X+Q+Z

Hi John,
In fact I am still a little bit confused because I had read the
?effect help
and B1 combined as one mean
(the baseline)? or is it something else? Does this number actually
tell me anything
useful (2.716)??
What does the model (y = intercept + ??) look like then? I can't understand
how both factors (A and B) can have the same intercept?
Thanks in advance!!
Gustaf Granath
but I guess that
should not be a problem.
For code and data, see below.
Cheers,

My code so far:
#Creating data
c(6.34,13.38,17.87)-y1
c(0.85,1.88,2.33)-y2
c(0,1.5,3)-x
cbind(y1,y2,x)-mydata
data.frame(mydata)-mydata
with(mydata, tapply(y1,x,mean))-mean.y1
with(mydata
-gam(y~s(x),data=mydata)
#Model including the factor Site. id=1 to get the same smothing
parameter at each factor level.
mod.with.site-gam(y~Site+s(x,by=Site,id=1),data=mydata)
#AIC for the two models
AIC(mod.no.site,mod.with.site)
Thanks,
Gustaf Granath (phd student
a factor variable for the
site:time interaction (i.e. one level for each combination of site and time)
but that would be pushing it a bit for this number of data.

Julöl? (Christmas beer)
That would explain it, I suppose
