coxboost

Formula interface for function <code>CoxBoost</code> of package <code>CoxBoost</code>.

survival

Validation of risk predictions obtained from survival models and
competing risk models based on censored data using inverse weighting and
cross-validation. Most of the 'pec' functionality has been moved to 'riskRegression'.

coxboost function

<dl><dt>formula</dt>
<dd>An event-history formula for competing risks of the
form <code>Hist(time,status)~sex+age</code> where <code>status</code> defines
competing events and right censored data. The code for right
censored can be controlled with argument <code>cens.code</code>, see man
page the function <a href="/link/Hist?package=pec&version=2025.06.24" data-mini-rdoc="pec::Hist">Hist</a>.</dd>
<dt>data</dt>
<dd>A data.frame in which the variables of formula are
defined.</dd>
<dt>cv</dt>
<dd>If <code>TRUE</code> perform cross-validation to optimize the
parameter <code>stepno</code>. This calls the function <code>cv.CoxBoost</code>
whose arguments are prefix controlled, that is <code>cv.K=7</code> sets
the argument <code>K</code> of <code>cv.CoxBoost</code> to <code>7</code>. If
<code>FALSE</code> use <code>stepno</code>.</dd>
<dt>cause</dt>
<dd>The cause of interest in competing risk models.</dd>
