bssmle_aipw | R Documentation |
Routine that performs B-spline sieve maximum likelihood estimation with linear and nonlinear inequality and equality constraints
bssmle_aipw(formula, aux, data, alpha, k)
formula |
a formula object relating survival object |
aux |
auxiliary variables that may be associated with the missingness and the outcome of interest |
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 event type 1. If α2 = 1, the user assumes the proportional odds model for the event type 2. |
k |
a parameter that controls the number of knots in the B-spline with 0.5 ≤ |
The function bssmle_aipw
performs B-spline sieve maximum likelihood estimation.
The function bssmle_aipw
returns a list of components:
beta |
a vector of the estimated coefficients for the B-splines |
varnames |
a vector containing variable names |
varnames.aux |
a vector containing auxiliary variable names |
alpha |
a vector of the link function parameters |
loglikelihood |
a loglikelihood of the fitted model |
convergence |
an indicator of convegence |
tms |
a vector of the minimum and maximum observation times |
Bv |
a list containing the B-splines basis functions evaluated at |
