title: Python BoxCox function yields empty array
body: <p>Trying to learn and use <code>scipy.boxcox</code>. But the results of boxcox are simply an empty array instead of a transformed set of data.</p>
  
  <p>I have tried giving BoxCox data in both array, tuple, and list format.</p>
  
  <pre><code>import pandas
  import psycopg2
  import numpy
  from scipy import stats
  
  .../...
  
  
  StarsArray = numpy.array(results)
  
  BoxCoxStars = scipy.stats.boxcox(StarsArray)
  
  BoxCoxResults = scipty.stats.boxcox(results)
  </code></pre>
  
  <p>I start with an array that is (6xxxxxx, 1) and/or a list that is 6xxxxxx. I'm expecting the boxcox transformation to provide a tuple that is 6xxxxxx and/or (6xxxxxx, 1).</p>
  
  <p>Howerver, I get a tuple that simply has the values of: (Numpy array, Numpy array). I get these results when I use either an array or list.</p>
