...tics, incorporating interaction effects etc.). The final prediction at the end however would be through a glm object (called fit.glm). Then, I think so, it would be no problem to calculate a Nagelkerke R squared measure and an AUC value (for example with the pROC package) following the script: BaseRate <- table(Data$Y[[1]])/sum(table(Data$Y)) L(0)=Likelihood(Null-Model)= (BaseRate*log(BaseRate)+(1-BaseRate)*log(1-BaseRate))*sum(table(Data$Y)) LIKM <- predict(fit.glm, type="response") L(M)=Likelihood(FittedModell)=sum(Data$Y*log(LIKM)+(1-Data$Y)*log(1-LIKM)) R2 = 1-(L(0)/L(M))^2/...

...overfits and barely beats the base rate if it builds a complicated tree. But the Kappa numbers go the opposite direction, and here's where I'm not sure what's going on. The examples in the vingette show Accuracy and Kappa being positively correlated. I thought Kappa was just (Accuracy - baserate)/(1 - baserate), but the reported Kappa is definitely not that. Suggestions? Aside from looking for a better model, which would be good advice here, what metric would you recommend? Thank you! -Harlan [[alternative HTML version deleted]]

Dear baseRs, I recently made a mistake when renaming data frame columns, accidentally creating an NA column. I found the following strange behavior when negative indexes are used. Can anyone explain what happens here. No "workarounds" required, just curious.

I have run into a problem when do loops with lots of elements in CentOS (I am a new user after using Ubuntu for many years). I am attaching two scripts, one called Looping_Centos_minimal_bug_OK.R which runs fine. I simply repeat a function call in it 15 times. However, if I repeat that function call 16 times, as in this one, Looping_Centos_minimal_bug_breaks.R I get the error, Error: unexpected

Hi, apologies if this question has been asked before; is there anyone working on a flac player for the Android G1? Is anyone interested in working on such a player?

Hello, I am new to this list. I have (and all Trukish users of Samba) trouble with Turkish charactes (iso8859-9)with Samba. I saw some character definition tables in charcnv.o (in sources). I couldn't understand the logic. A part of the table for iso8859-2 is /* MSDOS Code Page 852 -> ISO-8859-2 */ update_map("\241\244\242\364\243\235\244\317\245\225\246\227\247\365");
