Arguments
eps
Iteration continues until the relative change in the log partial
likelihood is less than eps. Must be positive.
toler.chol
Tolerance for detection of singularity during a Cholesky
decomposition of the variance matrix, i.e., for detecting a redundant predictor
variable.
iter.max
Maximum number of iterations to attempt for convergence.
toler.inf
Tolerance criteria for the warning message about a possible
infinite coefficient value.
outer.max
For a penalized coxph model, e.g. with pspline terms, there
is an outer loop of iteration to determine the penalty parameters; maximum
number of iterations for this outer loop.
timefix
Resolve any near ties in the time variables. (Floating
point representation
error can cause actual tied times to appear distinct.)
