This flow zone prepare the covariates necessary to run a multivariate model. The model is a standard survival model called the [Cox Model](https://en.wikipedia.org/wiki/Proportional_hazards_model#The_Cox_model), and it run entirely using the [Visual Machine Learning Lab](https://developer.dataiku.com/latest/concepts-and-examples/ml.html). 

Once trained, the model is deployed and can be used in other sections of the flow.
