Hypothetical data to be used in examples; t=5 and the landmark time = 2.
data(ExampleData)
A list with 6 elements representing 1000 observations from a control group and 1000 observations from a treatment group:
s1
Time of the occurrence of the surrogate outcome for treated observations.
x1
The observed event or censoring time for treated observations; X = min(T, C) where T is the time of the primary outcome and C is the censoring time.
delta1
The indicator identifying whether the treated observation was observed to have the event or was censored; D =1*(T<C) where T is the time of the primary outcome and C is the censoring time.
s0
Time of the occurrence of the surrogate outcome for control observations.
x0
The observed event or censoring time for control observations; X = min(T, C) where T is the time of the primary outcome and C is the censoring time.
delta0
The indicator identifying whether the control observation was observed to have the event or was censored; D =1*(T<C) where T is the time of the primary outcome and C is the censoring time.
Note that the time of the surrogate outcome is used in all functions only if the surrogate outcome occurs before the minimum of the event time and censoring time.
