<li><p>Computation: <code><a href="acc.html">acc</a></code> can be computed in 2 ways:</p>
<p>(a) from <code><a href="prob.html">prob</a></code>: <code>acc = (prev x sens) + [(1 - prev) x spec]</code></p>
<p>(b) from <code><a href="freq.html">freq</a></code>: <code>acc = dec_cor/N = (hi + cr)/(hi + mi + fa + cr)</code></p>
<p>When frequencies in <code><a href="freq.html">freq</a></code> are not rounded, (b) coincides with (a).</p></li>
