title: Pseudo R-squared for glm.cluster object
body: <p>I have estimated several glms with cluster robust standard errors using the function <code>glm.cluster()</code> from the <code>miceadds</code> package in R.</p>
  <p>Unfortunately, the function does not automatically calculate a pseudo R-squared.
  Moreover, I am unable to find a package for calculating a pseudo R-squared that is compatible with <code>glm.cluster</code>. So far, I have tried <code>rcompanion</code>'s <code>nagelkerke()</code>, <code>fmsb</code>’s <code>NagelkerkeR2()</code> and even <code>psfmi</code>'s <code>rsq_nagel()</code>.</p>
  <p>Did anyone else face this problem before and do you know how to resolve it without writing one's own function?</p>
