Mixed Models: Contribution of random variable to final estimate
Dear all,
We want to test if the invasiveStatus is predicted by the amount (quant) of animals arriving to a country of a certain species (taxonid). We are using lmer to perform the model.
The model is:
lmer(invasiveStatus~I(log(quant+1))+I(log(inDegree+1))+(1|taxonid)+(1|country), family=binomial,data=td),
where invasiveStatus is a binary variable, quant and inDegree are integer variables, and taxonid and country are factor variables.
The fixef output is
(Intercept) I(log(quant + 1)) I(log(inDegree + 1))
-15.6338288...

Power Law Exponents
...evised the following:
> linf <- as.data.frame.table((table(lin)),mode="numeric")
> linx = as.vector(linf$lin, mode="numeric")
> liny = as.vector(linf$Freq, mode="numeric")
> plot(linx, liny, pch=3, log="xy",main="Log-log", xlab="Indegree",
ylab="Frequency - Indegree")
> abline(lm (log10(vouty) ~ log10(voutx)))
This gives me the semblance of the plot I want but the exponent is wrong
and I have severe doubts about its correctness.
As I am neither a mathematician or statistician, I would be very
grateful for commen...
