[aGuyLearning]

Description of feature

Pass along arguments of the models in _sa.py and write output to Andata object.

Regression Models

cox_ph

• add arguments of liefelines function
• write output to anndata object
• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

weibull_aft

• add arguments of liefelines function
• write output to anndata object
• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

log_logistic_aft

• add arguments of liefelines function
• write output to anndata object
• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

Univariate Models

nelson_aalen

• write output to anndata object
• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

weibull

• add arguments of liefelines function
• write output to anndata object
• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

kaplan_meier

• key_added keyword (work in progress) for new entries
• make everything after adata, duration_col keyword only ("*,")

Suggest to have everything after everything after adata, duration_col, event_col as keyword only, as we have this pattern now already for kaplan_meier and its still simple enough
