Currency return calculations
Dear sir, I am extremely sorry for messing up the logic
asking for help w.r.t. my earlier mails
I have tried to explain below what I am looking for.
I have a database (say, currency_rates) storing datewise
currency exchange rates with some base currency XYZ.
currency_rates <- data.frame(date =
c("12/31/2010", "12/30/2010", "12/29/2010",

Optimisation and NaN Errors using clm() and clmm()
Dear List,
I am using both the clm() and clmm() functions from the R package
'ordinal'.
I am fitting an ordinal dependent variable with 5 categories to 9
continuous predictors, all of which have been normalised (mean
subtracted then divided by standard deviation), using a probit link
function. From this global model I am generating a confidence set of 200
models using clm() and the

question related to fitting overdispersion count data using lmer quasipoisson
Dear R-helpers:
I have a question related to fitting overdispersed count data using lmer.
Basically, I simulate an overdispsed data set by adding an observation-level
normal random shock
into exp(....+rnorm()).
Then I fit a lmer quasipoisson model.
The estimation results are very off (see model output of fit.lmer.over.quasi
below).
Can someone kindly explain to me what went wrong?
Many thanks in

Odp: Currency return calculations
My mistake sir. I was literally engrossed in my stupid logic, and while doing so, overlooked the simple and very effective solution you had offered. Sorry once again sir and will certainly try to be very careful in future.
Thanks again and have a great weekend sir.

Parametric Survival Models with Left Truncation, survreg
Hi,
I would like to fit parametric survival models to time-to-event data
that are left truncated. I have checked the help page for survreg and
looked in the R-help archive, and it appears that the R function survreg
from the survival library (version 2.16) should allow me to take account
of left truncation. However, when I try the command

A new pixman release 0.33.2 is now available. This is a release candidate for
a stable 0.34.0 release.
This release comes after little more than 1 year since the previous release
(0.32.6). Therefore, the git log is quite long and there are multiple changes,
fixes and enhancements.
The main changes are:
- ARMv6 - Many fast paths implementations were added

Thank you very much for your reply. Your code work well with this example.
I modified a little to fit my real data, I got an error massage.

Precision in R
Greetings.
I'm trying to recreate in R some regression models I've done in SAS,
but I'm not getting the same results. My advisor suspects this may be
due to differences in precision between R and SAS. Does anyone know
where I can find specifications for R's type double? (It doesn't seem
to be in the R Language Definition.) Thanks in advance for any help

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all,
I've started looking at the GlobalMerge pass, enabled by default on
ARM and AArch64. I think we should reconsider that, at least for
AArch64.
As is, the pass just merges all globals together, in groups of 4KB
(AArch64, 128B on ARM).
At the time it was enabled, the general thinking was "it's almost
free, it doesn't affect performance much, we might as well use it".

[LLVMdev] IR Passes and TargetTransformInfo: Straw Man
Hi, Sean:
I'm sorry I lie. I didn't mean to lie. I did try to avoid making a
*BIG* change
to the IPO pass-ordering for now. However, when I make a minor change to
populateLTOPassManager() by separating module-pass and non-module-passes, I
saw quite a few performance difference, most of them are degradations.
Attacking
these degradations one by one in a piecemeal manner is wasting

[LLVMdev] IR Passes and TargetTransformInfo: Straw Man
Andy and I briefly discussed this the other day, we have not yet got
chance to list a detailed pass order
for the pre- and post- IPO scalar optimizations.
This is wish-list in our mind:
pre-IPO: based on the ordering he propose, get rid of the inlining (or
just inline tiny func), get rid of
all loop xforms...
post-IPO: get rid of inlining, or maybe we still need it, only
