cochran Q test
Dear all,
I am trying to look for a built in function that performs the cochran Q
test.
that is, cochranq.test(X)
where X is a contingency table (maybe a matrix or data.frame).
The output will naturally be the test statisitcs, p-value, etc.
A quick search on Google gives me the cochran.test in the 'outlier' package,
but I had a look at the description of the test and it doesn't look

Help with cochran.test
Hi,
I have been trying to use the function cochran.test from the Outliers
package to test for homogeneity of variance. This works well except when
I use transformed data. Would anyone have an idea why it doesn't work
and how I could do the cochran test on transformed data?
Thanks,
Stephanie

cochran-grubbs tests results
Hello,
I'm new in this R world and I don't know much about statistics, but now I
have to analize some data and I've got some first queries yet:
I have 5 sets of area mesures and each set has 5 repetitions.
My first step is to check data looking for outliers. I've used the outliers
package. I have to use the cochran test and the grubbs test in case I find
any outlier. The problem

Defining environments within functions
How can I define environments within a function so that they are visible
to calls to a sub-function?
I have defined an objective function,
ProfileErr = function(params,...)
which I would like to optimize using standard routines (optim,
nlminb,....) but which contains auxiliary variables which need to be
updated along with params. No optimization routine in R that I have
found has facilities

Cochran-Mantel-Haenszel test
Hello,
I have some satellite tag time-at-depth (TAD) frequency data that I
would like some help with.
The data was transmitted via satellite as percent time spent in each of
7 depth bins (0m, 0-1m, 1-10m, 10-50m etc.), binned over 6-hour
intervals. I categorized each row of data corresponding to a date and
time into summer vs. winter, and day vs. night, and then summed and

using "cochran.test()" as a "mcnemar.test()" ?
Hello all
I wish to perform a mcnemar.test() for a 5X5 matrix.
Wikipedia tells me (http://en.wikipedia.org/wiki/Cochran_test) I should turn
to cochran.test.
The only place I found it was in the "outliers" package, but the command
cochran.test() acts differently then mcnemar.test() , and doesn't take a
table as input.
Any ideas on how to use it ?

problem with 'integrate'
Hello -
I am having a problem with the function 'integrate'. I am running R
on OSX (R 2.5.1).
I am trying to suppress the error message when 'integrate' attempts
to integrate across a parameter set giving a non-finite function
value. I'm using it in a MCMC / simulated annealing algorithm, and
it is entirely possible that some parameter sets will give non-

[LLVMdev] copy instructions
The mem2reg pass will rewrite allocas and loads and stores to SSA
virtual registers. Essentially it's a transformation from non-SSA to
SSA form. That said, I don't know if you want your students to
implement their own SSA transformation.

R and ACML
While I recently received some very helpful files and email from Kevin
Hendricks for compiling with ATLAS, thought I'd first have a stab at
ACML. Having problems, which I suspect are trivial to solve:

[LLVMdev] copy instructions
It is my understanding, the alloca memory routines are used
for forcing variables to be allocated on the stack frame -- which
you would want for source level debugging.
When SSA registers are used, LLVM will decide what goes into
registers and what will spill over to the stack frame.
I want the latter.

print method like print.anova()
I have a print method for a set of statistical tests, vcdExtra::CMHtest,

symbolic matrix elements...
Normally, I do symbolics in Maple, or Mathematica, but I'm trying to
write a simple script for students to handle some *very* simple
calculations (for other purposes) with matrix or vector elements, where
the elements are coded symbolically. What I've tried with *partial"
success is use of the tilde (~) operator. So, for example, consider a

Quick question on Cochran-Mantel-Haenszel test
Dear List,
I am looking for what B.S.Everitt refers to as Cochrane Method for testing
independence in combined 2x2 contingency tables. Is it the same method as
the Cochran-Mantel-Haenszel Chi-Squared Test for Count Data in R?
Thanks,

imbalanced classes
Hi Andy,
I know this topic has been discussed before on the R-help, but I was
wondering if you could offer some advice specific to my application.
I'm using the R random forest package to compare two classes of data,
the number of cases in each class relatively low, 28 in class 1 and 9
in class 2. I'd really like to use R environment to analyze this data,
