Fitted values and residuals from glmmPQL (MASS package)
Dear All,
I would like to analyse the residuals from a generalized linear mixed model (GLMM) that I estimated, with random effects, by means of the command glmmPQL, from the MASS package.
It is not very clear to me what the actual residuals to analyse are (Y - Yhat): I obtain two columns of residuals, of which the first are population residuals, and the second refer to the grouping used in the

Marginal effects in negative binomial
Dear All,
I carry out negative binomial estimations using the glm.nb command from the MASS package.
Is there a command or a simple procedure for computing marginal effects from a glm.nb fitted object?
If these are the same as for a Poisson fitted object (glm), my question remains how to compute them.
Thanks in advance for your help.

Problem with glm.nb estimation
Dear All,
I've been using already for a year glm.nb() from the MASS package.
But today, R gave me an error message when estimating one of my usual
models:

Percentage effects in logistic regression
Dear ALL,
I'm trying to figure out what the percentage effects are in a logistic
regression. To be more clear, I'm not interested in the effect on y of a
1-unit increase in x, but on the percentage effect on y of a 1% increase in
x (in economics this is also often called an "elasticity").
For example, if my independent variables are in logs, the betas can be

Profiling with LLVM.
Dear Duncan,
Thank you a lot for your feedback. I have a problem though. The branch
weights counters overflow in some files and thus I get incorrect numbers.
Is there any way to find a workaround for that? Is is supposed to be a
known bug or is it something that needs configuration on my part?
Again, thank you a lot for your reply.
Best Regards,

Profiling with LLVM.
Dear Duncan,
I am generating branch-weights annotated IR files as described in the
documentation of LLVM, using profiling with instrumentation.

Joint significance of more regressors in summary
Dear All,
I was wondering if it is possible to generate a regression summary (it does
not matter at this stage if from an lm or for example a glm estimate) in
which to obtain the joint significance of a set of regressors?
Examples could be looking at the joint significance level of a polynomial,
or of a set of exogenous variables of which is of interest the linear
combination suggested by the

anova for plm objects
Dear All,
I'm looking to perform an ANOVA between two nested panel fixed effects models. I tried with anova, as well as with waldtest. anova tells me there is no method available for plm objects, while waldtest tells me my models are not nested. I think they are instead. The difference between the two models is that in the second I let the regression coefficients of a given variable variate

Find enclosed the patch with the fastart implementation for vorbis (for

Now is based on size in bytes and the buffers are sent all together with

waldtest and nested models - poolability (parameter stability)
Dear All,
I'm trying to use waldtest to test poolability (parameter stability) between
two logistic regressions. Because I need to use robust standard errors
(using sandwich), I cannot use anova. anova has no problems running the
test, but waldtest does, indipendently of specifying vcov or not. waldtest
does not appear to see that my models are nested. H0 in my case is the the
vector of
