How to bind models into a list of models?
Hi R-helpers,
I have a character object called dd that has 32 elements each of which
is a model formula contained within quotation marks. Here's what it
looks like:
> dd
[1] "lm(y ~ 1,data=Cement)" "lm(y ~
X,data=Cement)" "lm(y ~ X1,data=Cement)"
[4] "lm(y ~ X2,data=Cement)" "lm(y ~

R's AIC values differ from published values
Using the Cement hardening data in Anderson (2008) Model Based Inference in
the Life Sciences. A Primer on Evidence, and working with the best model
which is
lm ( y ~ x1 + x2, data = cement )
the AIC value from R is
model <- lm ( formula = y ~ x1 + x2 , data =
cement )
AIC ( model )
64.312
which can be converted to AICc by adding the bias

MuMIn package, problem using model selection table from manually created list of models
The subject says it all really.
Question 1.
Here is some code created to illustrate my problem, can anyone spot where I'm going wrong?
Question 2.
The reason I'm following a manual specification of models relates to the fact that in reality I am using mgcv::gam, and I'm not aware that dredge is able to separate individual smooth terms out of say s(a,b). Hence an additional request,

how to selection model by BIC
Hi All:
the package "MuMIn" can be used to select the model based on AIC or AICc.
The code is as follows:
data(Cement)
lm1 <- lm(y ~ ., data = Cement)
dd <- dredge(lm1,rank="AIC")
print(dd)
If I want to select the model by BIC, what code do I need to use? And when
to select the best model based on AIC, what the differences between the

small error in regression tests
I just r-sync'ed the r-devel version of R-1.7.0 (2003-03-11), compiled it

with the message stating that "object cement was not found". It looks like
this piece of the regression test is new to version 1.7. The the piece of

Sum weights of independent variables across models (AIC)
Hello,
I'd like to sum the weights of each independent variable across linear
models that have been evaluated using AIC.
For example:

> dd <- dredge(lm1, beta = TRUE, eval = TRUE, rank = "AICc")
> get.models(dd, subset = delta <4)

delta AIC for models with 2 variables using MuMIn
Dear List,
I want to ask a AIC question based on package library(MuMIn)
The relative importance of 16 explanatory variables
are assessed using delta AIC in a generalized linear model.
Please kindly advise if it is possible to show models
with any two only certain variables.
Thank you.

I asked a similar question and got a great help for models
with only one variable as below.

AIC in MuMIn
Hello,
I am using package MuMIn to calculate AIC for a full model with 10
explanatory variables.
Thanks in advance in sharing your experience.
Q1
In the AIC list of all models, each model is differentiated by model number.
Please kindly advise if it is possible to
find the corresponding explanatory variable(s) for the model number.

SRV records.
Hi all,
A slightly hypothetical one here... but after Samba (Winbind actually)... looks up the list of AD server for a doman from DNS... what method does it use to decide which is the correct (most local?) domain controller to connect to/log in to?
What will it's behaviour be if it connects to one, or two which don't have connectivity.

Listing AD group members
Hi,
Ive been trying to work out how to get wbinfo to list members of a specific
AD group, rather than list groups a specific user is in.
So far I have had no luck... In fact im not sure its possible with wbinfo.
Is there another tool which could do this?

Oh, I assumed you meant -d10, since -d0 turns off all debug output, so the output is long, but I get:-

Windows pre-requisites for login with winbind?
Hi!
Indeed!, this sounds like good advice... there are certainly bugs, I had to get the 7.04.5 package from "proposed" to get resolve a PAM library issue!... although I suppose that's a packaging problem.
What is the best way to get an updated Samba package here, I'm trying to make this system reproduceable, I have a single script that builds the entire container, and sets up

I have krb5-config krb5-user, but not libpam-krb5... I'm slightly fuzzy about how this works, but I thought the interaction with kerberos was implemented via winbind, so I wasn't expecting this package to be installed... certainly there is no dependency that has pulled it in.

question about bayesian model selection for quantile regression
Hi All:
Recently I am researching my dissertation about the quantile model selection
by bayesian approach. I have the dependent variable(return) and 16
independent variables and I need to select the best variable for each
quantile of return. And the method I used is the bayesian approach, which is
based on calculating the posterior distibution of model identifier. In other
words, I need to obtain
