)
a character string indicating whether the log-rank type estimating equation or the Gehan-type estimating equation (when available) will be used.
a character string specifying the equation solver to be used for root search.
a positive numerical value specifying the absolute error tolerance in root search.
a character string indicating either to improve the proportional rate model via
the generalized method of moments (cppl = "GMM"
) or empirical likelihood estimation (cppl = "EL"
).
This option is only used when model = "cox.HH"
.
a list of (up to two) weight functions to be combined with the weighted pseudo-partial likelihood scores.
Available options are "Gehan"
and "cumbase"
,
which correspond to the Gehan's weight and the cumulative baseline hazard function, respectively.
Alternatively, the weight functions can be specified with function formulas.
This option is only used when model = "cox.HH"
.
a list contains the initial guesses used for root search.
an logical value indicating whether parallel computation will be
applied when se = "boot"
is specified in reReg()
.
an integer value specifying the number of CPU cores to be used when
parallel = TRUE
. The default value is half the CPU cores on the current host.
max number of iteration used when model = "cox.HH"
.
a logical variable denoting whether some of the
intermediate results of iterations should be displayed to the user. Default is FALSE
.
a positive numerical value specifying the small constant used in heuristic adjustment of the borrow strength method.
