Questions about survival prediction

[HelloWorldLTY]

Hi, thanks for your great work. I wonder for these metrics in EvalSurv, how to use them evalaute model prediction performance directly.

I think only these three metrics: Brier Score, Negative Binomial Log-Likelihood, and Administrative versions of Brier Score and NBLL, these three metrics' higher values mean worse model.

Is my understanding correct? Thanks.
