IWKMEIV {otrKM} | R Documentation |
The (S)IWKMEIV estimator.
Description
Given a predetermined t0 and eta, calculate t0-year potential survival probability based on the (S)IWKMEIV estimator.
Usage
IWKMEIV(eta, datalist, ps, t0, smooth = TRUE)
Arguments
eta |
The parameters of the regime. |
datalist |
A list used to calculate the (S)IWKMEIV estimator including treatment named |
ps |
A list including the probability of receiving instrument given baseline covariates named |
t0 |
A predetermined time. |
smooth |
A logic variable indicating wether a smoothed version should be used. |
Details
More details can be found in references.
Value
Estimated potential survival probability given eta and t0.
