----------------------------------
Hi [~mengxr] and [~yanboliang],
For the log-linear model for censored survival data, I believe the most
commonly used and easy to parallel methods are based on the exponential/Weibull
distribution of the survival time. The algorithm is to optimize the log
likelihood. So I think we could start with stochastic gradient descend for
large scale data. Can I chime in and contribute for this jira as well?

> We want to add basic log-linear models for survival analysis. The
> implementation should match the result from R's survival package
> (http://cran.r-project.org/web/packages/survival/index.html).
