cross-validation complex model AUC Nagelkerke R squared code
...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))...

caret's Kappa for categorical resampling
...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!

`[.data.frame`(df3, , -2) and NA columns
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.

Thanks.

Tuýrkish Character Set
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");
