I have a data frame with a number of observed and predicted values by classification as shown below: Count Volume FCLASS 1 55000 60000 Grade Separated 2 43000 39000 Grade Separated 3 26000 26500 Major Arterial 4 19500 20000 Major Arterial ... There are four classes here: Grade Separated, Major Arterial, Minor Arterial, and Collector I am looking to compute the following information FCLASS cor(Count,Volume) Grade Separated 0.999 Major Arterial 0.999 Minor Arteria...

Hello forum! I am currently having trouble getting R to recognize one of my pch characters. Here's what I have: legend(120, 40, c("SAL-arterial", "SAL-portal", "GLP-1-arterial", "GLP-1-portal"), bty="n", col=c("black"), pch=19:15:21:22, pt.bg="white", pt.cex=2:2:2:2, lty=1, lwd=2, text.col="black", cex=1.3) Now, SAL-arterial and SAL-portal should be a black circl...

Buenos días, Soy Cristian Rodelo y quería haceros una pregunta. Tengo un conjunto de datos en los que a un grupo de sujetos se les realizaron medidas de tensión arterial a lo largo de 24 horas. En promedio 4 determinaciones horarias. Es decir que cada sujeto se le realizaron 4 determinaciones horarias durante 24 horas. Bien, quiero determinar la trayectoria longitudinal de las mediciones de acuerdo con identificación de grupos que tengan una trayectoria diferent...

Hola, estoy intentando calcular la ganancia de información para una serie de variables (series temporales con distinta longuitud, ej: Presion Arterial, Frecuencia cardíaca,...) en relación con una variable binaria (0:paciente no muere; 1:paciente muere). Para ello voy a usar la función information.gain de la libreria FSelector. Sabeis si es posible calcular la ganancia de información para variables que tienen distinta longuitud?? es que en el...

Hello - The final schedule for the Asterisk birds-of-a-feather meeting (as an adjunct to the VON conference) in Boston looks like this: Tuesday, September 23rd at 8:15 at VinnyT's of Boston near the Hynes Convention Center. We'll try to get a corner booth in the "downstairs room", and look for the guy wearing the blue button-down shirt with VON logos on the breast pocket

I have a batch of data in each line of data contains three values, calcium score, age, and sex. I would like to predict calcium scores as a function of age and sex, i.e. calcium=f(age,sex). Unfortunately the calcium scorers have a very "ugly distribution". There are multiple zeros, and multiple values between 300 and 600. There are no values between zero and 300. Needless to say, the

Recently, I was able to create a workable Centos 4.4 "Live USB" on my 1G Lexar Firefly pendrive using the steps in http://linux.web.psi.ch/livecd/usbdisk.html. At the moment, it is doing its job, so I probably won't focus too much more on it. One thing that is annoying, although doesn't cause a problem is that on powerdown and reboot, the cd rom drive ejects - of course, there

I am analyzing data on a study of the effects of Coronary Artery Bypass Graft (CABG) on cognitive function, as measured by a score from an objective test. I have 140 people who receive the CABG surgery and 92 controls, with four measurements of cognitive function over time (at 0, 3, 12 and 36 months). I have fitted a linear mixed model using lme with a random intercept for subject and a random

Dear All, I would like to find something ( references, code,..) to implement a comparison of three treatments in an observational study using the 'Propensity Score'. Any help is much appreciated.

Dear all, I am comparing logistic regression models to evaluate if one predictor explains additional variance that is not yet explained by another predictor. As far as I understand Baron and Li describe how to do this, but my question is now: how do I report this in an article? Can anyone recommend a particular article that shows a concrete example of how the results from te following simple

Hello, I've checked the ML, but I don't find anything related to CentOS 4.5 (4U5) (missed it ?) Does the 4.5 will be out these days, or will it be released after the CentOS 5 ? Thanks, Pierre Bourgin

Hello, this is a little bit off-topic (even if it have to work on CentOS ;-) I'm looking for a tool to manage a small Public Key Infrastructure, with creation/revocation of certificates X.509, export in PKCS#12 format and have the ability to handle CSR (Certificate Signing Request). I've wrote my own script to perform it (openssl command line based): it's a good way to
