Exact observation scheme (no censoring)

Creates an observation functor that records the exact failure time with no censoring. This is the trivial case — included for completeness and for explicit use in Fisher information comparisons.

Usage

observe_exact()

Value

Observation functor: function(t_true) returning a list with t (exact time), omega ("exact"), and t_upper (NA).

Examples

obs <- observe_exact()
obs(42.5)  # list(t = 42.5, omega = "exact", t_upper = NA)
#> $t
#> [1] 42.5
#> 
#> $omega
#> [1] "exact"
#> 
#> $t_upper
#> [1] NA
