Instead of predicting the TTE itself the trick is to let your machine learning model
output the *parameters of a distribution*. This could be anything but we like the

The next step is to train the algo of choice with a special log-loss that can work
with censored data. The intuition behind it is that we want to assign high

To use the model one needs basic tte-transforms of raw data. To consume the models we
need weibull related functions for the final output.
