Hi, I used subset command, like this: grupoP = subset(dados, grupos=='P', select=c(mortos, vivos, doses, percevejos, p)) and the variables in select option are numeric. I tried fit a model with command: ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses), family=binomial(logit), data=grupoP) and the output is: > ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses),

Hi Samba people .. I'm quite new in here and I'd like to share a problem I'm experiencing. I've installed a 1.9.18p10 samba serve onto a HPUX 10.20 box . One of the problem I'm investigating on is that even if the " hide dot files" is explicitely specified in the smb.conf file , when I map a resource from a NT server I see all the "dot" files and

Dear all, I have a question with respect to counting process formulation of the coxph(survival) model. I have two groups of observations for which I have partitioned each observation into two distinct time intervals, namely, entry day till day 13, and day 13 till death or censorship day (of course the latter only for the observations that survived the first 13 day interval), and added a

Hello, I am currently trying to simulate data and analyze it using the frailty option in the coxph function. I am working with recurrent event data, using counting process notation. Occasionally, (about 1 in every 100 simulations) I get the following warning: Error in coxph(Surv(start, end, censorind) ~ binary + uniform + frailty(subject, : X matrix deemed to be singular; variable 2 My

Sipura has implemented auto-answer in version 0.9.5 of the SPA-841 firmware. However, it is implemented via the Call-Info header, which Asterisk stable doesn't currently support. The attached patch implments a quick hack to support the Call-Info header from the Dial() application by way of setting the CALL_INFO variable. For example, the following macro can be used to dial up a single

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems

Hey All, I'm having problems with samba/windows file attributes. I'm using roaming profiles (Win2000) with Samba serving as the PDC. Samba also stores the profiles.

Basically, I create a *read-only* file in my window profiles directory
