similar to: seq() function accuracy inacceptable

Full_Name: Johannes Prix Version: 2.1.1 OS: WinXP, SuSE Linux Submission from: (NULL) (137.208.41.195) The seq-command produces unnescessary inaccurate results, which can be extremely annoying. I absolutely do not see the nescessity of numerical garbage to appear in the following simple case. E.g. try this: > seq ( 61.55 , 62.00 , by=0.01 ) - round ( seq ( 61.55 , 62.00 , by=0.01 ) ,

Hello developers, I recently participated in a public listening test that was held by German magazine c't. They had two categories, 64 kbps and 128 kbps. I only participated in the 64 kbps test where there were 7 .wav files, with 1 of them the original one and the other 6 being encoded with different encoders. Without knowing which file was encoded with which encoder you had to give each

Hi I believe the dt() function in stats has small areas of inaccuracy. SmallRangeMostDetaileddf150.png shows this occurring in the 10-11th decimal place. MyD4 is computed using Myt_NC(), at the bottom of BugL.R - my function is very slow due to using mpfr, but i believe accurate to the accuracy of genhypergeo() which it uses - 14-15 dp. LargeRangeDiffdf150.png, which is difference

Hi, I think I have identified a inaccuracy in dchisq when the non-centrality parameter is non-zero and large. Here's a little test: sys.dchisq.test <- function(N = 100000,mean = 0) { z <- rnorm(N,mean = mean, sd = 1) x <- z^2 xmin <- min(x) xmax <- max(x) br <- seq(xmin,xmax,length = 101) dbr <- br[2]-br[1] hist(x,br) p <- dchisq(br,df = 1,ncp =

seq.default() tests for the relative range of the from and to arguments (see excerpt below) and returns from (only) when the relative range is small. The problem is that "small" is too large.

Hi, how can I prevent files/directories like /var/run/mariadb from being deleted on reboot? Lighttpd has the same problem. This breaks services and makes servers non-restartable by anyone else but the administrator who needs to re-create the needed files and directories every time and has to figure out what selinux labels they need. This causes unnecessary downtimes. This is entirely

Hi, I have the response variable 'Y' and four predictors say X1, X2, X3 and X4. Assuming all the assmptions like Y follows normal distribution etc. hold and I want to run linear multiple regression. How do I run the stepwise regression (forward as well as the backward regression). >From other software (i.e. minitab), I know only X1 and X2 are significant so my regression equation

Hi guys, Anyone know what this error with deliver is (v1.1.1)? 2008-07-03T09:45:19+01:00 mail4 deliver(alexander): Panic: file mail-index-transaction.c: line 642 (mail_index_transaction_lookup): assertion failed: (seq >= t->first_new_seq && seq <= t->last_new_seq) Seen a few of these this morning.

I wonder what is the history of "seq" and "seq.int"? >From "help(seq)", one reads that "'seq.int' is an internal generic which can be much faster but has a few restrictions". And indeed, "seq.int(1,99,by=2)" is over 40 times faster than "seq(1,99,by=2)" in a quick test I just did. This is not surprising given that

Hello list I'm facing a little security problem I get A LOT (3 a minute) a such a message mail dovecot-auth: pam_winbind(dovecot): request failed: No such user, PAM error was unknown user (13), NT error was NT_STATUS_NO_SUCH_USER I'd like to know which is the user name used in such attempts How can I get such info without raising log level to an inacceptable level (which would

This is a message for someone familiar with the implementation. Superficially the R code for seq.default and the C code for seq.int appear to be semantically very similar. My question is whether, in fact, it is intended that behave identically for all inputs. I have found two cases so far where they differ, first that seq.int will coerce a character string to a real (via Rf_asReal) whereas

I was going through this example of maxent use: http://cran.r-project.org/web/packages/maxent/maxent.pdf # LOAD LIBRARY library(maxent) # READ THE DATA, PREPARE THE CORPUS, and CREATE THE MATRIX data <- read.csv(system.file("data/NYTimes.csv.gz",package="maxent")) corpus <- Corpus(VectorSource(data$Title[1:150])) matrix <- DocumentTermMatrix(corpus) # TRAIN/PREDICT

Hi, I have two sets of sensitivity, specificity, positive predictive value, and negative predictive value, and accuracy from two tests on the same subjects. Is there an R package that does such paired comparisons? Thanks, Gang Chen

Dear all, I'd like to measure the prediction accuracy of a model I have derived from poisson regression. Can somebody help me with suggesting a good approach please? Thanks very much in advance. Best wishes, Des [[alternative HTML version deleted]]

Hi all, I''ve tried to look for this info in previous messages but had no luck. I''ve a 2.4.20 kernel on an Intel arch., all TC is configured and it seems to work. Anyway, I''ve had some troubles in configuring TBF via tc: 1. when I configure burst or minburst to be, say, 1500b, when I peek the configuration with "tc -s qdisc" the answer is that

Hey guys, I've finished my work on reading vorbis files (straight reading at either PCM sample lengths, or time lengths). However, I've run across a question. When you call vorbis_synthesis_read, I assume that increments the internal ptrs so you don't get the same data twice. The question is, what happens if you call vorbis_synthesis and vorbis_synthesis_blockin? Does the next call

Hello, I have two classifications. How can I compare the overall-accuracy of these classifications to each other? Is there a possibility within R to test if the achieved overall-accuracy for the classifications are differing significantly? Additionaly, are the McNemar-Test and Broker-Test implented in a package of R? Thank in advance for your help, Markus
