A model to add

[emenand]

Hello,
I would like to thank you for your valuable survival analysis package pycox which helped us to fulfill our research project.
We used the pycox code to test an improved neural network survival model based on N-MTLR (DOI: 10.21203/rs.3.rs-2259784/v1).
We added the ranking loss of DeepHit to N-MTLR, it results in similar C-index but better IBS performance.
The code hook is pretty simple and I was wondering if you would be interested in adding this model to your package.
Regards,
Elena
