I have already finished the initial implementation of AFT using L-BFGS, and it
can produce the same result as the [R function |
https://stat.ethz.ch/R-manual/R-devel/library/survival/html/survreg.html] test
on the [Larynx cancer data |
http://www.mcw.edu/FileLibrary/Groups/Biostatistics/Publicfiles/DataFromSection/DataFromSectionTXT/Data_from_section_1.8.txt].
I will submit the PR after correcting code format and adding more test cases.
I think you can comment and review it in one or two days.
