Ancillary arguments for controlling survtrans fitting

Ancillary arguments for controlling survtrans fitting

Usage

survtrans_control(
  abstol = 1e-04,
  reltol = 0.001,
  fdev = 1e-05,
  maxit = 300,
  verbose = FALSE
)

Arguments

abstol

the absolute tolerance for ADMM primal/dual residuals. Default is 1e-4.

reltol

the relative tolerance for ADMM primal/dual residuals. Default is 1e-3.

fdev

the minimum fractional change of the augmented Lagrangian for convergence. The algorithm stops when \(|L^{k} - L^{k-1}| / (|L^{k-1}| + 1) < fdev\), where \(L\) is the augmented Lagrangian. This provides a fallback when primal-dual residuals oscillate under non-convex penalties. Default is 1e-5.

maxit

the maximum number of iterations for the proposed algorithm. Default is 300.

verbose

a logical value indicating whether to print messages during the fitting process. Default is FALSE.

Value

A list with components abstol, reltol, fdev, maxit, and verbose.
