Please forgive a straight stats question, and the informal notation. let us say we wish to perform a liner regression: y=b0 + b1*x + b2*z There are two ways this can be done, the usual way, as a single regression, fit1<-lm(y~x+z) or by doing two regressions. In the first regression we could have y as the dependent variable and x as the independent variable fit2<-lm(y~x). The second

...it's already been covered, but I'm stumped... I'm using rsync to backup some file systems to a remote host. The transport is openssh-2.9.9p2. The problem does not occur when the transport is rsh. I'm invoking rsync as follows: rsync -RlHptgoD --numeric-ids -e "ssh" -rzx --stats . remotehost:/nfs/mirror But it hangs when there are large numbers of files in the "." filesystem. If I run with -vvv, I see lots of make_file entries as send_file_list starts sending the list of files to the remote host, but then it freezes after around 4500 to 6500 make_file me...

I can't find a way to retrieve z values and p-values from the output from lmer in the lme4 package. How is this done? Rick B.

Does anyone know how to get PhysX (http://www.nvidia.com/object/physx_8.09.04_whql.html) working? Some games, for example Pirates of the Burning Sea, require that PhysX is installed. This is what I get when I run the installer: Code: fixme:system:SetProcessDPIAware stub! fixme:iphlpapi:NotifyAddrChange (Handle 0x7d2129f8, overlapped 0x7d2129dc): stub fixme:shell:DllCanUnloadNow stub

Hi, I have been having a tedious issue with lmer models with lots of factors and lots of levels. In order to get the basic information at the beginning of the print out I also have to generate these enormous tables as well. Is there a method command to leave off all of the effects and correlations? Or, do I have to go to string commands?

Hello All, I would like to retrieve some of the results from the lmer(...) function in library lme4. If I run a model, say fm.1 <- lmer(y ~ 1 + (1 | x), data = dog) and try names(fm.1), I get NULL. Is there anyway to retrieve the information? Thanks

Javier, Creo que aquí aplica la ley de Linus que dice: "Dado un número suficientemente elevado de ojos, todos los errores se convierten en obvios". La persona que revisa y encuentra un error no necesariamente tiene que ser la misma que la que lo escribe. Una motivación muy importante al compartir un código es la de recibir los beneficios del control de calidad por parte de tus pares.
