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 f...

...us variables X. What I do is to predict class probabilities with multinom() in nnet(), obtaining a predicted classification Ypred and then compute the percentage P(obs) of objects classified the same in Yobs and Ypred. My problem now is to figure out whether P(obs) is significantly higher than chance. I opted for a crude permutation approach: compute P(perm) over 10000 random permutations of Yobs (i.e., refit the multinom() model 10000 times randomly permuting Yobs) and consider P(obs) as significantly higher than chance if higher than the 95th percentile of the P(perm) distribution. Now,...

Hi @all! I have two questions: - First, am I right that the chance of getting the same 32-bit rolling checksum is 1/2^16 and to get the same 128-bit MD5 Hash is 1/2^127? - Finally I want two know if it is possible to change an amount of blocks manually? e.g. I made a 100 MB file with "dd if=/dev/zero of=/home/test.xyz bs=1M count=100" and know I want...

...g random changes in a vector: Say you have a vector (1, -1, -1, 1, 1, -1). I want each value in the vector to have a probability that it will change signs when this vector is regenerated. For example, probability = 50%. When the vector is regenerated, the first value in the vector (1) has a 50% chance of switching to -1. If I regenerated this vector 10 times, 5 of the times it would switch to -1. Similarly, I need each value in the vector to have this same probability of switching signs when the vector is regenerated, and each value's chances of doing so is independent of the other values....

Is there an R function that I can use to calculate the p-value from the Z statistics computed for the relationship between chance and observed proportions in predictions. More sprcifically I am refering to proportional chance criteria (Cpro). Details are in Huberty's book on Applied discriminant analysis, unfortunately our library has misplaced the book. I got some details from the following page http://marketing.by...

...weaver 8. Because of Bug http://bugs.winehq.org/show_bug.cgi?id=7372 Dreamweaver is de facto unusable under Wine because an essential function doesn't work: Pasting into the design view from clipboard is impossible. My question: Is Crossover "technically" identic to Wine? Is there a chance that Crossover will not have a bug, which Wine has?

All, I have Picasa, which is wine based, installed. Is there any chance it is causing trouble for a wine install? What is the dll search order? Has anyone had success installing the windows version under wine? Thanks, Dan

...elf-service restore function to our users using their IMAP client of choice.. Our idea was to use a snapshot (under ZFS, btrfs, whatever) and have it available to the user in a namespace. Unfortunately, but understandably, dovecot doesn't like the mdbox structure to be read-only. Is there any chance to change that? In the meantime, we could use a read-write snapshot, but we wouldn't like the users to really do changes to that snapshot. Our next attempt is to use ACLs, but it's a bit hard to gt the ACLs to the correct place in the snapshots, at least for thousands of users. Our curre...

Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

...ch a circumstance should have code to handle it, or throw an exception. Which makes me curious, if I submitted a patch that got rid of llvms use of abort()s all over the place, and replaces them with exceptions (the program dies either way if it is unhandled, but with exceptions you at least get a chance to handle it and recover), what is the chance it would be accepted, especially since I see no usage of exceptions at all (even if it passes through the C api, think about it, if an abort occurs, the program dies, if an exception is thrown through the C api, the program still dies, either way it die...
