title: Evaluating (not Sampling from) Beta Distribution in Numpy
body: <p>I am trying to calculate <code>Beta(x; a, b)</code> for many specific values of <code>x</code>, taking <code>a = 1, b = 25</code>. There is a beta function in numpy, namely <code>numpy.random.beta(a, b)</code>. But it samples from the beta distribution, rather than evaluating for specific values of <code>x</code>.</p>
  
  <p>Any quick way around this, rather than having to code in the formula for beta?</p>
