Extracting overdispersion estimates from lmer amd glm objects
...e models as well as calculate qausi-AIC values. I have been unable to do this, despite consulting a number of manuals and searching the R-help. I am imaging that in theory it should be possible with some call to attr(), but i have so far had no success.
An example model output would be:
> modeltest<-lmer(Coleodactylus_amazonicus_N~USD + (1|site),data=SFArray,family=poisson,method="Laplace",control=list(usePQL=FALSE, msVerbose=TRUE))
> summary(modeltest)

nls making R "not responding"
Here is the code I am running:
library(nls2)
modeltest<- function(A,mu,l,b,thour){
out<-vector(length=length(thour))
for (i in 1:length(thour)) {
out[i]<-b+A/(1+exp(4*mu/A*(l-thour[i])+2))
}
return(out)
}
A=1.3
mu=.22
l = 15
b = .07
thour = 1:25
Yvals<-modeltest(A,mu,l,b,thour)-.125+runif(25)/4

Help with Krige.conv using linear models
...predict values in a grid. But?one set of my data appears to be
linearly correlated for the first 5000 meters and not correlated beyond
that. I have been having problems using krige.conv() to get a decent
kriged map using the linear model. The code I am using from my data is
as follows:
>modeltest=variofit(variotest, weights=?cressie?, cov.model=?linear?,
ini.cov.pars=c(80,1))
The output parameters are tausq = 9.855, sigmasq = 0.0087, phi=1.0
>krig=krige.conv(data, krige=krige.control(type.krig=?ok?,
obj.model=modeltest), locations=pred.grid)
At this point, krig$predict values have...

shoulda installation troubles
...have shoulda working.
I''m using rvm with rails 3.1 and ruby 1.9.2
I added
group :test do
gem "shoulda"
end
to the Gemfile, and then run bundle install, thus the gem is installed,
and it is featured in the list running gem list --local.
but whenever I add something like
class ModelTest < Test::Unit::TestCase
should_not allow_value("blah").for(:email)
end
in a testfile, running that test with ruby -Itest
test/unit/model_test.rb
I get an error undefined method `allow_value'' for ModelTest:Class
Am I missing something?
should I manually require shoulda? where...
