Dear Ellen,
You're using the Poisson distribution. There is no error (noise) term in a
glmm with Poisson distribution.
1) The random part seems to be quite complicated given the sample size.
(1|site) is probably sufficient. Note that your design is not nested but
crossed.
2) Overdispersion is lik

Similarly to what can be read on help(qqplot), however using Rayleigh
distribution:
library(VGAM)
p <- ppoints(100)
x <- qrayleigh(p)
y <- rrayleigh(100)
qqplot(x,y)
qqline(y, distribution = function(p) qrayleigh(p),
prob = c(0.1, 0.6), col = 2)

If you have a quantile function for any distribution, you can make a QQ
plot using ppoints() and the quantile function.
The Rayleigh distribution isn't in base R, but Google says it is

Hi,
You have panel data or cross-sectional data? In the case you use
cross-sectional data and "countries" are your observations (no repeated measure
of them) and you regress the country-dummies on your residuals of the forgone
regression, then there are as many regressors as observations. Conse

Hello,
I wonder if you might be able to help me. I'm enrolled in an R programming
course through Coursera. I've done well so far--though it's been

the loop functions (like "lapply") work.

Dear Jeff,
I'm tempted to say that a scatterplot without points is an oxymoron, but that
wouldn't be very helpful.
Actually, the scatter3d() function used by the Rcmdr is in the car package. The
Rcmdr 3D scatterplot dialog doesn't provide for suppressing the points, but if
you add radius=rep(0
You should really be asking Coursera for help with its course.
However you can figure this out by breaking down your commands
into small steps and seeing what each step gives. This is an advantage
of an interactive system like R. E.g., suppose you start with

Wouldn't you just stop using scatter3d?
