1. Confidence interval for the survival probabilities and quantiles.
Probability/Quantile can be expressed as a (explicit/implicit) functional of the CDF or a functional
of the cumulative hazard. So, we can do it in two different ways.
For a given T , the probability P (X ≤ T ) = F (T ), and it can be written as F (T ) = ∫ I [s≤T ] dF (s).
In the example below I took T = 1. Also, here (P-value > 0.05) iff (-2LLR < 3.841). So, instead of
looking at the P-value, we examine the -2LLR value.
