Details EM Survival Node

[mat_n]

I am performing a survival analysis using SAS EM and want to understand the underlying methods/algorithm in detail.

However, I did not find such information online or in any manual. The documentation only provides an in-depth description of how to apply the node.

Might be that I am missing an obvious source, so any hint is much appreciated.

Dear Miss Czika,

Due to my data structure, I am also curious how a tree-based survival analysis would perform. However, I could not find any SAS procedure or EM-Node which is capable of dealing with time-varying covariates of counting process style data.

Did I miss something about that?

Do you have any thoughts about how the EM survival node deals with conditionally related covariates (b can be equal to 1 only if a is equal to 1)? In such settings, either intercation terms or tree structures should be desirable.

Many thanks in advance!
