ating whether a intercept exists or not. Default value is <code>TRUE</code> for all 
functionals. Intercept may also be removed if a "-1" is present in <code>formula</code>. If "-1"
is present in <code>formula</code> but <code>intercept = TRUE</code> is specified, the model will fit
without an intercept. Note that when <code>fnctl = "hazard"</code>, the intercept is always set to
<code>FALSE</code> because Cox proportional hazards regression models do not explicitly estimate 
an intercept.</p></dd>
