print.summary.speffSurv
prints a formatted summary of results. In the initial section, right-sided formulas
defining the optimal selected functions in the randomization and censoring space are printed. Further, an inferential
table is generated with point and interval estimates of the log hazard ratio, standard error estimates, and Wald test
p-values using both the proportional hazards and covariate-adjusted estimation methods. At least five significant
digits are printed.
A list with the following components:
tab |
inferential table for the treatment effect. |
method |
search technique employed in the model selection procedure. |
formula |
a list with components rndSpace and censSpace containing formula objects for the optimal
selected linear regression models that characterize the optimal elements in the randomization and censoring space,
respectively. Set to NULL if fixed=TRUE . |
fixed |
a logical value; if TRUE , the efficient estimator utilized all baseline covariates specified in the
formula. Otherwise, the automated selection procedure was used to identify covariates that ensure optimality. |
