Is there a way to create a BRR svrepdesign from a survey design when the number of PSUs is odd in one or more stratum? Creating a JKn svrepdesign with that condition works okay, but when I tried to create a svrepdesign with type="BRR" I get an error and this message: "Can't split with odd numbers of PSUs in a stratum" I get that message when I tell it...

Hi, I have been experimenting with the new Survey package. Specifically, I was trying to use some of the functions on the public-use survey data from NHIS (2000 Sample Adult file). Error 1): The first error I get is when I try to specify the complex survey design. nhis.design<-svydesign(ids=~psu, probs=~probs, strata=~strata, data=nhis.df, check.strata=TRUE) Error in svydesign(ids =

Hello, Is there a way to get complex sample variances in the survey package on summary statistics other than means? If not, can they be added to a future version? It would be be great to have them on totals, quantiles, ratios, and tables (eg row percent, columns percent, etc). Thanks. Fred --------------------------------- [[alternative HTML version deleted]]

...etwork cable, wondering if it's in wake-on-lan; I've tried connecting to it via its management port, and *zip*. I'm not going to do, as several folks' posts that I googled (been at that for hours), cut the cable and solder in an on/off switch. I have taken the lid uff, reseated the PSUs, and the cable connecting to the front panel, and nada. Anyone got any ideas? mark

I've used nut for simple configurations before but now one has grown to a more complex setup and can't seem to find any info online. I would like to have single central nut master monitor a bank of UPSs for a whole rack of servers with redundant PSUs. So UPS A1 ---> Server group A PSU 1 UPS A2 ---> Server group A PSU 2 UPS B1 ---> Server group B PSU 1 UPS B2 ---> Server group B PSU 2 I've read numerous pages about using MINSUPPLIES for redundant UPS->PSU setups, but nothing about setting up groups so that server bank B can...

Our server has 2 UPS on 2 PSUs. At 8am, someone unplugged one UPS. At 8:10, they plugged it back in, but turned off the load - presumably to stop the beeping. So the system is still up on 1 PSU, and can talk to both UPS. Can't I turn on the load via USB? upsc output for the UPS that is off: battery.charge: 100 batte...

...to compute coefficient estimates for Cox regression. I have noticed the p-values output are based on normal distribution (like in coxph); however in svyglm (and in other software, such as Stata or SAS) the p-values are computed via the t distribution with degrees of freedom equal to the number of PSUs minus number of strata. I am wondering why there is a difference here? Thank you very much, Chirag Patel Stanford University cjp at stanford.edu

...al. As always, everything is 100% open source and free-as-in-beer! The major changes are: * SELinux and iptables are enabled and used. * Numerous slight changes made to the OS and cluster stack configuration to provide better corner-case fault handling. * Architecture refinements; ** Redundant PSUs, UPSes and fence methods emphasized. ** Monitoring multiple UPSes added via modified apcupsd ** Detailed monitoring of LSI-based RAID controllers and drives ** Discussion on hardware considerations for VM performance based on anticipated work loads * Naming convention changes to support the new A...

...about the survey package and nomenclature. For instance, given how I've described the survey/weighting, is my call to svydesign correct? I'm not sure I understand just what a "survey design" is. Where can I read up on this? What's a good reference for such things as "PSUs", "cluster sampling", and so on. I've tried the following code, which fails: > SurveyData <- read.spss("C:/Data/R/orange_delivery.sav", use.value.labels=TRUE, max.value.labels=Inf, to.data.frame=TRUE) > #================================================...

Dear WizaRds, I am struggling to compute correctly a cluster sampling design. I want to do one stage clustering with different parametric changes: Let M be the total number of clusters in the population, and m the number sampled. Let N be the total of elements in the population and n the number sampled. y are the values sampled. This is my example data: clus1 <-

Ok thank's for your time David, the PSUs, I have two old ones, are working very well. I simply put in new batteries and on they go :-). I'm using the PSUs mostly to secure my Raspberry PIs, which are notorious to fail (SD card) on power failures. Bye, jrb.

...- so it does not have to shut itself down. Even then however, verifying the setup without an `upsc` or managing it without `upsrw`/`upscmd`/... would be cumbersome (though possible with telnet or other clients), and a "primary"/"master" mode upsmon watching the UPS as powering 0 PSUs of that box is recommended to send out FSD commands etc. Not sure if we have example setups to power off such an UPS (as we would normally when the primary system is also fed by it and goes down last with special handling).

...s) - I found I'm vague now on who hits the big red button to shout that a particular power source device got critical - the upsmon in "master" role, or "upsd" that talks to all subscribed (indeed!) upsmon's and just some choose to stop asap (if they won't have enough PSUs powered) and others wait for them to pull the plug on UPS afterwards :) So if in a way upsd is a message broker between many clients actively emitting commands, pub-sub is an option. If upsd emits messages differently based on roles of registered clients - not so much. Note also that there techni...
