aftsem.control {aftsem} | R Documentation |
Control list for package
aftsem.control(
eps = 10^-5,
maxiter = 15,
gehan_eps = 10^-6,
optimx.alg = "BFGS",
variance.estimation = FALSE,
quantile.method = "br",
use.grad = FALSE
)
eps |
Convergence criterion |
maxiter |
Maximum iterations for algorithms |
gehan_eps |
Epsilon value for polynomial Gehan optimalization |
optimx.alg |
Algorithm that will be used in optimx minimalization (see optimx documentation for more details) |
variance.estimation |
If hellers sd will be estimated |
quantile.method |
Method used for quantile regression minimalization |
use.grad |
If excact gradient will be used instead of the numerical one, default is numerical == FALSE |
list of parameters above
When alternating the control list, one must write other variables also. Example: When user want to estimate the Hellers covariance matrix he would need to change the control list -> aftsem(....., control = list(variance.estimation = TRUE, use.grad = FALSE, optimx.alg = "BFGS))
