survreg.control           package:survival           R Documentation

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
