SolveH {depCensoring} | R Documentation |
This function estimates the nonparametric transformation function H when the survival time and censoring time are dependent given covariates. The estimating equation of H was derived based on the martingale ideas. More details about the derivation of a nonparmaetric estimator of H and its estimation algorithm can be found in Deresa and Van Keilegom (2021).
SolveH(theta, resData, X, W)
theta |
Vector of parameters in the semiparametric transformation model. |
resData |
Data matrix with three columns; Z = the observed survival time, d1 = the censoring indicator of T and d2 = the censoring indicator of C. |
X |
Data matrix with covariates related to T. |
W |
Data matrix with covariates related to C. |
Returns the estimated transformation function H for a fixed value of parameters theta.
