cwilcox - new version
...s/stats/versions/3.6.2/topics/wilcox.test . In an old paper I have written a formula where the evaluation can be done in a one-dimensional array that uses way less memory and is much faster. The paper itself is in German (you find a copy here: https://upload.wikimedia.org/wikipedia/commons/f/f5/LoefflerWilcoxonMannWhitneyTest.pdf), so I uploaded a translation into English (to be found in https://upload.wikimedia.org/wikipedia/de/1/19/MannWhitney_151102.pdf). I also looked at the code in R and wrote a new version of the code that uses my formulae so that a faster implementation is possible (code w...

predict.glm -> which class does it predict?
Hi, I have a question about logistic regression in R. Suppose I have a small list of proteins P1, P2, P3 that predict a two-class target T, say cancer/noncancer. Lets further say I know that I can build a simple logistic regression model in R model <- glm(T ~ ., data=d.f(Y), family=binomial) (Y is the dataset of the Proteins). This works fine. T is a factored vector with levels cancer,

Backup from Linux onto Win2K-share
...ba. How can I get rid of it? I've tried to use a different kernel (2.4.22) and I compiled as well as new Samba 3.0.1 from source (on a different machine). But I still have the problem. Whats wrong? (PS: NFS has a limit as well; 4 GB. But I need "unlimited" sizes) Regards Carsten L?ffler command ag mailto:carsten.loeffler@command.de ______________________________________________________________________ This message is intended for the addressee or its representative only.

...m still having a ticket at SAP to tell me which mechanism they use for the backup (TAR, STAR). --- Any more questions or ideas, guys?!

LASSO: glmpath and cv.glmpath
Hi, perhaps you can help me to find out, how to find the best Lambda in a LASSO-model. I have a feature selection problem with 150 proteins potentially predicting Cancer or Noncancer. With a lasso model fit.glm <- glmpath(x=as.matrix(X), y=target, family="binomial") (target is 0, 1 <- Cancer non cancer, X the proteins, numerical in expression), I get following path (PICTURE
