...it (dataset) to remove NAs. I reconstructed all my factor variables into binary variables with dummies (using model.matrix) I then used glmnet lasso to fit a cox model and select the best performing features. Then I fit a coxph model using only these feature. When I try to evaluate the model using pec and a bootstrap I get an error that the prediction matrix has wrong dimensions. Suddenly the cox object has 318 variables instead of 356 variables in the dataset. I don't know why this is happening. The cox object I assign to pec and the dataframe are both of the same size. However, once pec re...

Im trying to write a controller spec, but when I run it I get an error like the one below. I found Bug6707 (http://rubyforge.org/pipermail/rspec-devel/2007-March/002147.html ), but I get the error no matter how I run the spec ( whether I use rake or not) Any ideas? I am using 0.8.2 The Error: C:/rails/InstantRails/ruby/lib/ruby/...

Dear all, I would like to obtain the Brier score prediction error at different times t for an extended Cox model. Previously I have used the 'pec' function (pec{pec}) to obtain prediction error curves for standard Cox PH models but now I have data in the counting process format (I have a covariate with a time-varying effect) and it seems that the pec function does not support the counting process format, or am I doing something wrong? H...

Hello everyone, These are some questions about the 'pec' function in R. These questions deal with prediction error curves and their derivation. Prediction error curves are documented in, for example, "Efron-type measures of prediction error for survival analysis" by Gerds and Schumacher. I have detailed some syntax that I have used at t...

caching_thread()s do all their work under read access to extent_commit_sem. They give up on this read access only when need_resched() tells them, or when they exit. As a result, somebody that wants a WRITE access to this sem, might wait for a long time. Especially this is problematic in cache_block_group(), which can be called on critical paths like find_free_extent() and in commit path via commit_cowonly_roots(). This patch is an RFC, that attempts to fix this problem, by notifying the caching threads to give up on extent_commit_sem. On a system with...

We are trying to automate the running of our rspec tests for our Rails app on a build server using Capistrano. The problem is that Capistrano seems to think that the command called to run the model tests failed when in fact I believe it succeeded. I believe the problem has to do with the return code from the command I am running.. The command I am...
