<p>For <a href="mkinfit.html">mkinfit</a> or <a href="saem.html">saem</a> objects, a character vector of parameter

<h2>Details</h2>
<p>The method for hierarchical model fits, also known as nonlinear
mixed-effects model fits as obtained with <a href="saem.html">saem</a> and <a href="mhmkin.html">mhmkin</a>
checks if any of the confidence intervals for the random
effects expressed as standard deviations include zero, and if
the confidence intervals for the error model parameters include
zero.</p>

<div id="note">
<h2>Note</h2>
<p>All return objects have printing methods. For the single fits, printing
does not output anything in the case no ill-defined parameters are found.</p>
