Control list for package

Description

Control list for package

Usage

aftsem.control(
  eps = 10^-5,
  maxiter = 15,
  gehan_eps = 10^-6,
  optimx.alg = "BFGS",
  variance.estimation = FALSE,
  quantile.method = "br",
  use.grad = FALSE
)

Arguments

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

Value

list of parameters above

Note

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))
