...the confidence interval for the mean predicted Y, however, I need the confidence interval for the individual predicted Y. According to the stats text I looked at, I need to change the above formula to se.fit<-sqrt(apply(gradient, 1, function(x) sum(vcov(myNLSmodel)*outer(x,x))+NEWTERM)) where NEWTERM is NEWTERM<-myNLSmodel$m$deviance()/(nObservations - nParameters) So the problem is that while the confidence intervals are close to those provided by SAS, they are always smaller. This, in the end, makes a large difference for the application. Can anyone suggest how I might...

Hi all, I can't come over a problem with formula. Suppose I have a coxmod model with the following formula: > somemod$formula Surv(lebzeit, tot == 1) ~ sex + (alter >= 65) + diff3k + zelltyp_k_c + q_nuc_3k + kar_k80_g80 + stadium and I want to drop the stadium explanatory variable from the model with > update(somemod, ". ~ . - stadium") I get the following messages:

Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB. I'm using clang-3.9 and this configuration: -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
