debug
a flag for debugging, default FALSE
R6 CoxMaster
object
kosher()
Check if inputs and state of object are sane. For future use
CoxMaster$kosher()
TRUE
or FALSE
logLik()
Return the partial log likelihood on all data for given beta
parameter.
CoxMaster$logLik(beta)
beta
the parameter vector
a named list with three components: value
contains the value of the
log likelihood, gradient
contains the score vector, and hessian
contains
the estimated hessian matrix
addSite()
Add a url or worker object for a site for participating in the distributed computation. The worker object can be used to avoid complications in debugging remote calls during prototyping.
CoxMaster$addSite(name, url = NULL, worker = NULL)
name
of the site
url
web url of the site; exactly one of url
or worker
should be specified
worker
worker object for the site; exactly one of url
or worker
should be specified
run()
Run the distributed Cox model fit and return the estimates
CoxMaster$run(control = coxph.control())
control
parameters, same as survival::coxph.control()
a named list of beta
, var
, gradient
, iter
, and returnCode
#' @description ' Return the summary of fit as a data frame
summary()
CoxMaster$summary()
a summary data frame columns for coef
,
exp(coef)
, ' standard error, z-score, and p-value for each
parameter in the model following the same format as the
survival
package
clone()
The objects of this class are cloneable with this method.
CoxMaster$clone(deep = FALSE)
deep
Whether to make a deep clone.
