<dt>mult</dt>
<dd><p>A numeric vector of length 1 or the same length as
<code>which_pars</code>.
The search for the profile loglikelihood-based confidence limits is
conducted over the corresponding symmetric confidence intervals
(based on approximate normal theory), extended
by a factor of the corresponding component of <code>mult</code>.</p></dd>


<dt>num</dt>
<dd><p>A numeric scalar.  The number of values at which to evaluate the
profile loglikelihood either side of the MLE.  Increasing
