Bootstrap varince estimation for the estimated regression coefficients
bssmle_se(formula, data, alpha, k = 1, do.par, nboot, objfun)
formula |
a formula object relating survival object |
data |
a data frame that includes the variables named in the formula argument |
alpha |
α = (α1, α2) contains parameters that define the link functions from class of generalized odds-rate transformation models. The components α1 and α2 should both be ≥ 0. If α1 = 0, the user assumes the proportional subdistribution hazards model or the Fine-Gray model for the cause of failure 1. If α2 = 1, the user assumes the proportional odds model for the cause of failure 2. |
k |
a parameter that controls the number of knots in the B-spline with 0.5 ≤ |
do.par |
using parallel computing for bootstrap calculation. If |
nboot |
a number of bootstrap samples for estimating variances and covariances of the estimated regression coefficients. If |
objfun |
an option to select estimating function |
The function bssmle_se
estimates bootstrap standard errors for the estimated regression coefficients from the function bssmle
, bssmle_lt
, ro bssmle_ltir
.
The function bssmle_se
returns a list of components:
notconverged |
a list of number of bootstrap samples that did not converge |
numboot |
a number of bootstrap converged |
Sigma |
an estimated bootstrap variance-covariance matrix of the estimated regression coefficients |
