Draft Surv to classif pipeline #194

[studener]

No description provided.

[bblodfon]

• run document() to generate the docs and get the exported objects
• add tests
• make pipeline_survtoclassif (see pipeline_survtoregr) that uses the two PipeOps consesutively
• pammtools::as_ped => to base R => we import pammtools for now, no need to do anything further here
• add cut hyperparameter

In the end run some sanity check:

• use task generator to generate survival data
• use discSurv package + logistic regression -> compare to our pipeline (e.g. same coefficients, etc.)
• use misscpecified model (without covariate that has effect) and correctly specified model (with covariate with effect) to check that c-index, brier-score etc. have better values for correctly specified model
