title: what is meant by rv_frozen object in scipy?
body: <p>I am writing Python script to code for finding probability of Hypergeometric distribution. When I am using <code>hypergeom()</code> function in <code>scipy</code>, it is showing like below:</p>
  
  <pre><code>scipy.stats.distributions.rv_frozen object at 0*2519690
  </code></pre>
  
  <p>I have googled but couldn't find anything useful. I just wanted to know what does it actually mean? </p>
