Offset in GLMM
Dear R-list,
I try to adjust GLMM on incidence cancer data. Without random effect, in GLM
the command is, for example with sex effect,
glm(Observed~sex+offset(log(Expected)),family=poisson) because the observed
are Poisson distribued with parameter Expected*incidence rate. But know I
want to introduce random effect (for example spatial effect) and it seems to
me that the "offset" does

generic name of variables
Dear R-list,
I wish a very happy new year and send you a little question: I have
different variables which names are m1, m2, m4, .., m10, ... and want to
obtain for example mean of each of them without typing each mean(m1),
mean(m2), .... What is the solution for decomposing names in mXX?
With my best regards, EA.

compiled the source code
again and know it does. Please, download it again, and sorry for the
inconvenience.

Variables values on intersected intervals
Dear R-list,
i have a problem, in the framework of simulations, i want to vectorize for
earning time: a variable, say X, has values on intervals and an other
variable, say Y, has values on other intervals. For example
Inf Sup X
0 2 1
2 4 2
4 6 3
and
Inf Sup Y
1 3 1
3 5 2
5 7 3

critical value for HEGY test in uroot
R-users,
i have some time series and use HEGY seasonal UR tests in the uroot package.
But i have problems with interpretation of t and F statistics. Is there any
critical values for these tests in R? is anybody ever write a bootstrap of
these tests?
thanks for advance, with all my bests, erik.

StructTS
Dear R-list,
I try to use StructTS for some univariate time series, with a type="BSM". I
have two questions:
1-in the "fitted" value of the object, it seems to me that for getting back
fitted values, one have to add level, slope and seasonal (or "level"
contains already the two other ones)
2-i am really circumspect about the results of "KalmanForecast"

Age-period-cohort model
Dear R-list,
I think it's really a newbie question but ...
I try to model age-period-cohort models with polynoms in each effect. I have
for each level of age and period some cases -k- and persons-years -py-.
Models are A_xP_y:
log(k_age,period/py_age,period)=f(polynom(x),age)+f(polynom(y),period). For
exemple I try to adjust an A2P3 :

Intercept by level in GLM
Dear R-listers,
I have to explain "y", a continous variable, with two variables "t" and "p"
which are "factor variables": t is [1:12] and p is [1:18] (a value for y for
each combination t*p). OK, then I try to adjust models like: y=a_p + b*t (I
mean as many intercepts as levels of p) or y=a_p + b_p*t (as many intercepts
and coefficients for t as levels of

Object containing different classes
Hi,
i want to create an object which contains different classes: for example i
have some time series and test if ARIMA models are best than HoltWinters
models: for each of my time serie i want to collect in an unique object
which model was the best: for some it will be an HoltWinters class and for
some other an Arima class.
is there any solution?? thanks in advance, with my best, erik sauleau

New package: DCluster
Dear R users,
I am glad to announce the release of a new package for R: DCluster. It
implements a number of methods for the detection of clusters of disease.
It includes methods to test Poisson extra-variation (Chi-square test and
Potthoff-Whittinghill's test), Spatial Autocorrelation (Moran's I and
Geary's c), general clustering (Whittermore's statistic and Tango's

ts and stl functions - still a problem
Hi
I am still having problems with using the stl function, when I read the csv file into R into a file called tkr and use dim(tkr) the result is 132 1 which is fine.
When coerce it into a trime series using ts either:
tstkr <- ts(t(tkr), deltat=1/12) or
tstkr <- ts(c(tkr), deltat=1/12)
and use the stl function I get the following error:

Could anyone tell me how to extract pvalue from "lm" fitting?
Dear R people,
I have a naive question: after fitting "lm" to a data, I can't extract
the pvalue corresponding to a specific covariate in a direct way.
Could anyone give me a hint?
Thank you very much.

t-test pvalue
Hi all,
I have some t-test values, and I am trying to obtain the associated p-values.
Is 'pt' the right command? I wonder why 1) it returns different values for
x and -x, and 2) how to obtain a 2-sided p-value.
example [R version 2.0.1, WinXP]:
#if t=2.23 (df=10), the expected p-value is 0.05 for 2-sided and 0.025 for
1-sided t-test
pt (2.23,10)
[1] 0.9750788
pt (-2.23,10) #or pt
