update fit (removing insignificant variables)
HI,
I am not sure about the ?update() method.
You could try this:
set.seed(232)
mat1<-matrix(sample(1:100,80,replace=TRUE),ncol=8) #with 8 columns
dat1<-data.frame(mat1)
?names(dat1)[1]<-"Y"
?fit<-lm(Y~.,data=dat1)
res<-coef(summary(fit))
?res
#???????????????? Estimate Std. Error???? t value?? Pr(>|t|)

insignificant factors in regression model
Hi list,
I am building a regression model with categorical predictor variable coded
by treatment contrasts. The summary of the regression model shows that some
levels are significant while others are not. The significant ones show that
they are statistically significant from the basis factor (at level 0). How
do we generally deal with those insignificant levels? If they are used for

Insignificant variable improves AIC (multinom)?
Hi,
I am trying to specify a multinomial logit model using the multinom function from the nnet package. Now I add another independent variable and it halves the AIC as given by summary(multinom()). But when I call Anova(multinom()) from the car package, it tells me that this added variable is insignificant (Pr(>Chisq)=0.39). Thus, the improved AIC suggests to keep the variable but the Anova

How to exclude insignificant intercepts using "step" function
I posted this question way down at teh end of another thread realted to an
error in step, but that was stupid since it really is another matter
altogether. I should have posted it separately, as I have now done.
The code below creates a data.frame comprising three marginally noisy
surfaces. The code below (including a fix courtesy of David Winsemius that
avoids a step function error through use

Do we have to control for block in block designs if it is insignificant?
I am wondering if in a block experimental design (ex. triple square lattice), the block effect was not significant, is it all right not to include the block effect in an empirical model (even though the sampling was done from different blocks)? Or we are forced to control for the block effect in block designs anyway?
Thanks,
Julia

Tukey, planned contrasts or t-test without ANOVA? What is correct?
Dear R community,
I compare mean monthly body temperature between two age classes of turtles overwintering underground.
lm(body_tem ~ Month*Year*Age_Class)
TukeyHSD(aov(body_tem ~ Month*Year*Age_Class, a))
The Tukey HSD as well as the planned contrasts method showed significant differences between the two age classes, but insignificant differences between the two age classes at the same

Strange p-level for the fixed effect with lme function
Hello,
I ran two lme analyses and got expected results. However, I saw
something suspicious regarding p-level for fixed effect. Models are the
same, only experimental designs differ and, of course, subjects. I am
aware that I could done nesting Subjects within Experiments, but it is
expected to have much slower RT (reaction time) in the second
experiment, since the task is more complex, so it

FSMO / ldbsearch
Hi,
After a couple of unfortunate hardware failures and some not insignificant
amount of work to rebuild two of my DCs, I am trying to check that things
are now working correctly.
Looking at the wiki page on FSMO ownership, one suggestion is to run the
following ldbsearch command.. but this doesn't work for me.

Interpreting p values of gls in nlme
Dear all
I have undertaken some phylogenetic and non-phylogenetic regressions with
gls() in nlme with single preictor variables. A p value is associated with
the intercept (upper p value) and another with the predictor variable
(lower). Which p value is important? What does it mean if the intercept p
value is insignificant but the predictor is still significant?
Thanks a lot, and sorry for my

i do not get access to a physical disk with xen. I would like to install

I partioned the disk with cfdisk. Filesystem type is Linux (83). In my

Whitespace in SuperRedCloth
Up to now, the tests have been running with whitespace stripped out.
Newlines and tabs are insignificant in HTML, so I figured why bother
with them?
Now I realize why: they''re significant in pre tags and they also make

comparing glm models - lower AIC but insignificant coefficients

models (glm). I am trying to compare a model with a gaussian
distribution and an identity link function, and a poisson model with

dovecot.sieve shows up as a mailbox
Thanks for the help.
This did solve my problem, and created a little hiccup.
Namely, all the users that had email account LOST their mail. I am just
starting migrating to this new mail server setup, so mostly just
insignificant testing emails.
I am sure there is a way to recover the old mails? Doesn't matter, not
really much there.
