<p>
            All the code in this library is inside namespace boost::math.
          </p>
<p>
            In order to use a distribution <span class="emphasis"><em>my_distribution</em></span> you
            will need to include either the header &lt;boost/math/distributions/my_distribution.hpp&gt;
            or the "include all the distributions" header: &lt;boost/math/distributions.hpp&gt;.
          </p>
<p>
            For example, to use the Students-t distribution include either &lt;boost/math/distributions/students_t.hpp&gt;
            or &lt;boost/math/distributions.hpp&gt;
          </p>
<p>
            You also need to bring distribution names into scope, perhaps with a
            <code class="computeroutput"><span class="keyword">using</span> <span class="keyword">namespace</span>
            <span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">;</span></code>
            declaration,
          </p>
<p>
            or specific <code class="computeroutput"><span class="keyword">using</span></code> declarations
            like <code class="computeroutput"><span class="keyword">using</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">normal</span><span class="special">;</span></code> (<span class="bold"><strong>recommended</strong></span>).

              Some math function names are also used in namespace std so including
