Hi, im little bit confused about Cohen's Kappa and i should be look into the Kappa function code. Is the easy formula really wrong? kappa=agreement-chance/(1-chance) many thanks christian ############################################################################### true-negativ:7445 false-positive:3410 false-negativ:347 true-positiv:772 classification-aggrement:68,6% kappa=agreement-chance/(1-chance) = (0.686-0.5)/0.5=0.372 .....with function from library(vcd) Kappa(matrix(c(7445,3410,347,772),nrow=2)) value ASE Unweighted 0.1686882 0.011235188 We...

...I?m fitting a model with glm(family binomial). The best model counts 9 Variables and includes an interaction term that was generated by the product of to continuous variables (a*b). All variables are correlated under a value of 0.7 (Spearman rank order) While the estimates of both main effects are negativ, the resulting interaction term is positiv. This change of sign makes it difficult to interpret the model and above all, is this perhaps due to a bad variable choice ?

...pretty good software. Ths week I went to upgrade from 1.0pre7 to 1.0.1 and failed. The tincd process gets aborted inside the libcrypto library with OPENSSL_assert (inl >0). Tracking down that problem I found, that the EVP_DecryptUpdate gets called in meta.c with the last argument containing a negativ value (lenin is -204). The process sits in my server and waits for incoming connections. In the middle of the first connection handshaking (via a TCP connection), the server hosted process gets aborted. The remote end sees a timeout. For now I went back to 1.0pre8, but it would be great, to see t...

Hi, I have two questions. First, I'd like to compare a ZINB model to a negativ binomial model with the Vuong test, but I can't find how to performe it from the zicount package. Does a programm exist to do it ? Second, I'd like to know in which cases we have to use a double hurdle model instead of a zero inflated model. Many thanks, St??phanie Payet REES France R??s...

Hi, How do I can make a lagged scatterplot of two variables: Yt (nao) versus Xt-h (mei) if they have the following structure: >series mei nao Jan 1950 -1.036 0.55 Feb 1950 -1.133 3.31 Mar 1950 -1.259 0.81 Apr 1950 -1.027 1.60 May 1950 -1.399 -1.73 Jun 1950 -1.366 1.26 Jul 1950 -1.300 -0.87 . . . I've tried with lag.plot but I don't understanf how to use it Thanks in

Hello together, I am working on liquid water profiles of clouds and would like to describe these profiles in relation to a reference profile. What is the best way to do this ? RMSE would equal positiv and negativ deviations. Is it better to use a correlation coefficient ? What is the best way, espacially when I want to find out profiles with the same behaviour / shape, which are just more or less shifted / just have a different mean value ? Thanks for your help in advance ! Klemens Dipl.-Geogr. Klemens Ba...

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

Within a very large matrix composed of a mix of values and NAs, e.g, matrix A: [,1] [,2] [,3] [1,] 1 NA NA [2,] 3 NA NA [3,] 3 10 17 [4,] 4 12 18 [5,] 6 16 19 [6,] 6 22 20 [7,] 5 11 NA I need to be able to consecutively number, in new columns, the non-NA values within each column (i.e. A[1,1] A[3,2] and A[3,3] would all be set to one, and

I performed the update yesterday that included installing kernel 2.6.9-42.0.2.EL and replacing ethereal with wireshark. First, the trivial... Wireshark would not run from the KDE menu without editing the menu to change the command from "wireshark" to "kdesu wireshark" because dumpcap is at usr/sbin/dumpcap instead of /usr/bin/dumpcap . Making the change causes wireshark to

Dear R folks, I need to simulate first passage times for iterated partial sums. The related papers are for example [1][2]. As a start I want to simulate how long a simple random walk stays negative, which should result that it behaves like n^(-?). My code looks like this. -------- 8< -------- code -------- >8 -------- n = 100000 # number of simulations length = 100000 # length of iterated sum z = rep(0, times=length + 1) for (i in 1:n) { x = c(0, sign(rnorm(length))) s = cumsum(x)...

For those of you that either have an older revision of my firewall document, or are otherwise keeping track of it, there is a new version available. The current version of the document is version 3.1. It's changed rather significantly in some areas.
