extracting pvalue from ANOVA with repeated measures
I made an ANOVA with repeated mesures
(aov(Mesure~Distance*Genre*Correct+Error(Sujet/(Distance*Genre*Correct)),
data)) and I would like to extract the pvalues.
The output is:

PLS method
dear all,
I am a new comer to R and statistic. Now I have a little confuse about the
package pls.
I have to use 5 components to form a model. There are strong relationship
between some of the components, which leads to the changes of the sign of
each coeficeince, of course this is unwanted when using the normal
regression way. So I choose the way of PLS, which is good at solve this kind

回复: cch() and coxph() for case-cohort
I tried to compare if cch() and coxph() can generate same result for
same case cohort data
Use the standard data in cch(): nwtco
Since in cch contains the cohort size=4028, while ccoh.data size =1154
after selection, but coxph does not contain info of cohort size=4028.
The rough estimate between coxph() and cch() is same, but the lower
and upper CI and P-value are a little different. Can we

cch function and time dependent covariates
----- begin included message
In case cohort study, we can fit proportional hazard regression model to
case-cohort data. In R, the function is cch() in Survival package
Now I am working on case cohort analysis with time dependent covariates
using cch() of "Survival" R package. I wonder if cch() provide this utility
or not?
The cch() manual does not say if time dependent covariate is

qda problem
Hi,
the following strange error appears when I use qda:
> qda1 <- qda(as.data.frame(mfilters[cvtrain,]),as.factor(traingroups))
Error: function is not a closure
That's also strange:
> qda1 <- qda(mfilters[cvtrain,],as.factor(traingroups))
Error in qda.default(mfilters[cvtrain, ], as.factor(traingroups)) :

poly() in lm() leads to wrong coefficients (but correct residuals)
Dear all,
I am using poly() in lm() in the following form.
1> DelsDPWOS.lm3 <- lm(DelsPDWOS[,1] ~ poly(DelsPDWOS[,4],3))
2> DelsDPWOS.I.lm3 <- lm(DelsPDWOS[,1] ~ poly(I(DelsPDWOS[,4]),3))
3> DelsDPWOS.2.lm3 <-
lm(DelsPDWOS[,1]~DelsPDWOS[,4]+I(DelsPDWOS[,4]^2)+I(DelsPDWOS[,4]^3))
1 and 2 lead to identical but wrong results. 3 is correct. Surprisingly

Repeated measures by lme and aov give different results
I am analyzing data from an experiment with two factors: Carbon (+/-)
and O3 (+/-), with 4 replicates of each treatment, and 4 harvests over a
year. The treatments are assigned in a block design to individual
Rings.
I have approaches this as a repeated measures design. Fixed factors
are Carbon, O3 and Harvest, with Ring assigned as a random variable. I

Can't find all levels of categorical predictors in output of zeroinfl()
Hello,
I?m using zero-inflated Poisson regression via the zeroinfl() function to
analyze data on seed-set of plants, but for some reason, I don?t seem to be
getting the output for all three levels of my two categorical predictors.
More about my data and model:
My response variable is the number of viable seeds (AVInt), and my two
categorical predictors are elevation (Elev) and Treatment

Rank Product
Hello Guys,
I'm using the package RankProduct to determine the differential expression of genes in 2 classes.
The importance of the thing is to know:
- How can I determine which class is the class of up-regulated genes and which to the down regulated gene
- How can i interpret the results :

Hello ,
I am compiling SPEC 2000 benchmarks with llvm .Got stuck with calculating "execution time" of all the .bc and native files.
The log for nightly test itself gives execution times but I am passing the bytecode files to my pass which gives another bytecode file.I have to calculate execution time of such bytecode and native files as well.If i simply do this:

Hello All,
Thanks for the reply.I can generate the reports by compiling Spec through llvm, but that couldn't resolve my problem.
I m trying to determine execution time for the bytecode and native files , which are obtained as a result of running my pass over the original bytecode .I am running these experiments on spec benchmark.
In SPEC we have command line tools such as runspec where
