rf2d</code> can successfully include a wide range of model types in
its inference functions.</p>
<p>For model identifiability, at least one linear restriction is necessary.
<code>mrf2d</code> always assume \(\theta_{0,0,r} = 0\) for all relative positions
\(r\).</p>
<p>Additionally, each family of restrictions may introduce other restrictions:</p>
    </div>


    <div id="-onepar-">
    <h2>'onepar'</h2>
    

<p>This family assumes the model is defined by a single parameter
by adding the restriction</p>
