Is there a method to calculate Huynh and Feldt adjustments for sphericity violations
Hi,
I'm getting to grips with using R to perform repeat measures
analysis of variance and was wondering is there a potted method to
obtain Huynh and Feldt or other adjustments for sphericity
violations?
Thanks

Huynh-Feldt R vs SAS Bug
Hi,
I'm using anova.mlm sphericity tests/corrections, and I'm getting
different values than SAS. In order to be able to use these values for
publications, I'd need to know more about the SAS bug that is mentioned
in the Reference Manual.
- What exactly causes the different values?
- Is it just a slight difference, or can I expect significant
differences in H-F/G-G epsilons and

Reproducing SAS GLM in R
Hi,
I'm still trying to figure out that GLM procedure in SAS.
Let's start with the simple example:
PROC GLM;
MODEL col1 col3 col5 col7 col9 col11 col13 col15 col17 col19 col21 col23
=/nouni;
repeated roi 6, ord 2/nom mean;
TITLE 'ABDERUS lat ACC 300-500';
That's the same setup that I had in my last email. I have three factors:
facSubj,facCond and facRoi. I had this pretty

H-F corr.: covariance matrix for interaction effect
Hi,
I'm still not quite there with my H-F (G-G) correction code. I have it
working for the main effects, but I just can't figure out how to do it
for the effect interactions. The thing I really don't know (and can't
find anything about) is how to calculate the covariance matrix for the
interaction between the two (or even n) main factors.
I've looked through some books

[LLVMdev] Multiclass patterns
Bill,
Sorry if I wasn't clear enough. I wasn't referring to multiclass's that
define other classes, but with using patterns inside of a multiclass to
reduce redundant code.
For example:
multiclass IntSubtract<SDNode node>
{
def _i8 : Pat<(sub GPRI8:$src0, GPRI8:$src1),
(ADD_i8 GPRI8:$src0, (NEGATE_i8 GPRI8:$src1))>;
def _i32 : Pat<(sub

How to improve, at all, a simple GLM code
Hi There,
I am trying to fit a logit model to some data in a CSV file in R.
Here is my code:
Prepared_Data = read.csv("Prepared_Data.csv", header=TRUE)
Prepared_Data
attach(Prepared_Data)
lrfit<-glm(C3~A1*B2*D4*E5,family = binomial)
anova(lrfit, test="Chisq")
write.csv(anova(lrfit, test="Chisq"), file="CWModelA.csv")
shell.exec("CWModelA.csv")

[LLVMdev] RFC: AVX Pattern Specification [LONG]
Here's the big RFC.
A I've gone through and designed patterns for AVX, I quickly realized that the
existing SSE pattern specification, while functional, is less than ideal in
terms of maintenance. In particular, a number of nearly-identical patterns
are specified all over for nearly-identical instructions. For example:
let Constraints = "$src1 = $dst" in {
