lmomRFA-package: regsimq()
Hi List! I?m using regsimq() from the ?lmomRFA?-package to calculate error bounds for diverse distributions. For example: regsimq(gumfit$qfunc, nrec = lmom.data$n, f = lcdfgum, boundprob = c(0.025, 0.975)) Several times I got this error massage: Fehler in quantile.default(ou, probs = boundprob, type = 6) : missing values and NaN's not allowed if 'na.rm' is FALSE So my question

"lmomRFA" package: error bounds/confidence intervals
Dear List I?m using the ?lmomRFA? package to fit different distributions to my data sample. To calculate the error bounds I used: regsimq(?) and sitequantbounds(?) So my questions are: Are error bounds and confidence intervals the same thing? And: Does regsimq(? boundprob = c(0.05, 0.95)) calculate the 90 or the 95% confidence interval? If error bounds and confidence intervals are

lmomco package and confidence limits?
Hello, I am using the lmomco package (lmom.ub and pargev) to compute the GEV parameters (location, scale, and shape), which are used to estimate return values. I was wondering how/if I can calculate upper and lower confidence (CI_u, CI_l) intervals for each return frequency using the GEV parameters to fill-in the table below? Xi (location) = 35.396 Alpha (scale) = 1.726 Kappa (shape) =

WinBind does not work well with Rational ClearCase (bug fix atta ched :)
Hello Samba, We tried to use samba-2.2.4-1 with Rational ClearCase and had a problem using WinBind. ClearCase requires the primary group id to be set to the clearcase users group. WinBind sets the primary group to something like DOMAIN_GROUP_RID_USERS. I am including the patch we made to samba-2.2.4 to get things working. I have added two new smb.conf options: winbind primary group //

WinBind does not work well with Rational ClearCase (bugfix atta ched :)
Andrew, Thank you for your suggestions. The real problem is Rational Technical support. When you pay someone 100k+ they tend to look for any excuse to deem you "unsupported". If you don't have your default group set to the clearcase user group, then technical support will decide that thats where your problem is! I am sure you know how that goes... I have solved problems

Group averages
Hello: I hope none of you will mind helping a newbie. I'm a student research assistant working with a large data set in which observations are categorized according to two factors. I'm trying to calculate the group mean and variance of a variable (called 'hsgpa' in the example data presented below) to each observation , excluding that observation. For example, if there are

Recommendation for dialplan in case of DDoS atta cks?
I'm trying to formulate a strategy for our interconnected Asterisk IAX peers to failover to the PSTN in the event of a DDoS. We currently use them like this: DID--->PRI--->Primary Asterisk--->IAX--->On-site Asterisk--->SIP This works fine, and everyone is happy. One of my concerns, though, is if we get DDoS'd - which happens probably once every couple of years. I'd

R cannot allocate a vector of size 5.4mb
Hi, I am trying to do mixed integer programming using R & Java. My input is a list of flight legs which is proportional to the number of times the loop is executed. The input is fed from java to R. I cannot avoid the for loops as it is part of the logic. I am running into a "cannot allocate a vector of size 5.4mb" error. The system memory available 16Gb and nearly 11Gb of it is

Lattice: Combining xyplot and histogram
Dear all, I am trying to create a lattice plot which consists of 1 xyplot and 2 histograms (each for x and y). My first try was like this: x<-rnorm(1000) y<-rnorm(1000) xy <- xyplot(y~x) hist.x <- histogram(x) hist.y <- histogram(y) print(xy, position=c(0, 0.2, 1, 1), more=TRUE) print(hist.x, position=c(0, 0, 1, 0.33),more=T) print(hist.y, position=c(0.8, 0, 1, 1)) Ok, this is
