ichotomous data (<span class="math inline">\(K = 1\)</span>) we use the Bernoulli distribution in the calculation of the scoring rules.</p></li>
<li><p>For binomial data and to account for over-dispersion we use the Beta-Binomial distribution. From the quasi-likelihood behind the GEE the variance of <span class="math inline">\(Y_{ijk}\)</span> is <span class="math inline">\(\mbox{var}(Y_{ijk}) = \phi K \pi_{ijk} (1 - \pi_{ijk})\)</span>, where <span class="math inline">\(\phi\)</span> is the over-dispersion
