title: unable to update statsmodels to version 0.8.0rc1 using conda
body: <p>I am unable to update my statsmodels v. 0.6.1 to 0.8.0rc1 using conda (I used conda because I have conda installed).</p>
  
  <p>I have tried several ways:</p>
  
  <ol>
  <li>conda install statsmodels (based on <a href="http://www.statsmodels.org/dev/" rel="nofollow">http://www.statsmodels.org/dev/</a>). Nothing
  happened, my version stays the same.</li>
  <li><p>conda update statsmodels. Still not updated, see below.</p>
  
  <blockquote>
    <p>C:\Users\E245713>conda update statsmodels
    Fetching package metadata .........</p>
    
    <p>Solving package specifications: ..........</p>
    
    <p>All requested packages already installed.</p>
    
    <p>packages in environment at    C:\Users\E245713\AppData\Local\Continuum\Anaconda3:</p>
    
    <p>statsmodels               0.6.1               np111py35_1</p>
  </blockquote></li>
  <li><p>Uninstalled statsmodels and installed it again, and it still installed the old version 0.6.1.</p></li>
  </ol>
  
  <p>I am using windows 7 Enterprise. </p>
  
  <p>Any ideas?</p>
