NaN in hurdle model please?
Simplify your model. Does your TandemRepeat have a lot of levels? Or is
your sample size very small?
Alain
Dear all,
I am
fitting a hurdle model in the following way:
HNB <-
hurdle(chro ~ as.factor(TandemRepeat)| as.factor(TandemRepeat), data =data_negbin_fin,
dist = "negbin")
But the std.
error for log(theta) = NA
Count model
coefficients (truncated negbin with log link):

Predicted values for zero-inflated Poisson
Hi all-
I fit a zero-inflated Poisson model to model bycatch rates using an offset term for effort. I need to apply the fitted model to a datasets of varying levels of effort to predict the associated levels of bycatch. I am seeking assistance as to the correct way to code this.
Thanks in advance!

mfrow and centering plots when there's an odd number
Let me start with an example:
par(mfrow=c(2,3))
for (i in 1:5){
x = rnorm(100)
y = .5*x + rnorm(100, 0, sqrt(1-.5^2))
plot(x,y)
}
Note that there's five plots and six spaces for those plots via mfrow,
leaving one row empty. Is there a way to have the bottom two plots
centered? I think it looks weird to have them left-justified. Thanks in
advance for the help!

Checking for normality and homogeneity of variance
Dear all,
I'm a beginner of R and I need to carry out some three-way mixed ANOVAs.
Following examples at http://personality-project.org/r/r.anova.html, I
managed to get the ANOVA part, but I don't know how can I check data
normality and homogeneity of variance in R (since they're the required
assumptions of ANOVA analysis).
Are there any special command/packages? Could anyone give me

Time Varying Coefficients
I'd like to estimate time varying coefficients in a linear regression using
a Kalman filter.
Even if the Kalman Filter seems to be available in some packages I can't
figure out how to use it to estimate the coefficients.
Is there anyway to do that in R?
Any help appreciated
Thanks

Using anova(f1, f2) to compare lmer models yields seemingly erroneous Chisq = 0, p = 1
Hello,
I am using R to analyze a large multilevel data set, using
lmer() to model my data, and using anova() to compare the fit of various
models. When I run two models, the output of each model is generated
correctly as far as I can tell (e.g. summary(f1) and summary(f2) for the
multilevel model output look perfectly reasonable), and in this case (see
below) predictor.1 explains vastly more
