title: statsmodel AttributeError: module 'scipy.stats' has no attribute 'chisqprob'
body: <p>I'm running the code below with statsmodel 0.8.0 which i believe is the latest. </p>
  
  <pre><code>import statsmodels.api as sm
  est = sm.Logit(y_train, x_train)
  result = est.fit()
  print(result.summary())
  </code></pre>
  
  <p>This is giving me an error saying:</p>
  
  <p>AttributeError: module 'scipy.stats' has no attribute 'chisqprob'.</p>
  
  <p>I dont seem to be able to find anything on stackoverflow or elsewhere to resolve this. Any help much appreciated.</p>
