em all states equiprobable.</p>
<p>A very simple prior is the so-called <em>K2</em> prior, which simply adds “1” to the count of every single state. A somewhat more sensible choice of prior is <em>BDeu</em> (Bayesian Dirichlet equivalent uniform prior). For BDeu we need to specify an <em>equivalent sample size</em> “N” and then the pseudo-counts are the equivalent of having observed <cite>N</cite> uniform samples of each variable (and each parent configuration).</p>
