survreg.control: Package options for survreg and coxph

Description

These functions check and package the fitting options for survreg and coxph

Usage

survreg.control(maxiter=30, rel.tolerance=1e-09, failure=1,
toler.chol=1e-10, iter.max, debug=0, outer.max=10)
coxph.control (eps = 1e-09, toler.chol = .Machine$double.eps^0.75, 
    iter.max = 20, toler.inf = sqrt(eps), outer.max = 10)

Arguments

maxiter

maximum number of iterations

rel.tolerance

relative tolerance to declare convergence

failure

value of status variable indicating failure

toler.chol

Tolerance to declare Cholesky decomposition singular

iter.max

same as maxiter

debug

print debugging information

outer.max

maximum number of outer iterations for choosing penalty parameters

eps

Tolerance to declare convergence for Cox model

toler.inf

An undocumented parameter

Value

• A list with the same elements as the input
