Hello I would like to compare the results obtained with a classical non parametric proportionnal hazard model with a parametric proportionnal hazard model using a Weibull. How can we obtain the equivalence of the parameters using coxph(non parametric model) and survreg(parametric model) ? Thanks Virginie

Do i have right to do that ? Thanks a lot. See my kde2dw function below : kde2dw <- functio...

Hello, Another French student in the rsync mailing list. I have been working on rsync this year for a documentation project for school and I would like to give some comment about rsync block size optimization first, and then to submit a way to make rsync choose by itself the optimal blocksize when updating a large number of files. Well, the first comment: during my work, I wanted to verify
