title: Pandas: Filtering on describe output (count)
body: <p>I am trying to limit the output returned by the describe output to a subset of only those records with a count great than or equal to any given number.</p>
  
  <p>My dataframe is a subset of a larger one, and is defined as:</p>
  
  <pre><code> df = evaluations[['score','garden_id']]
  </code></pre>
  
  <p>When I run describe on this,    </p>
  
  <pre><code>df.groupby('garden_id').describe()
  </code></pre>
  
  <p>I would like to filter the returned data to those records where count > a specified number.</p>
  
  <p>My output looks like:</p>
  
  <pre><code>Out[39]: 
                   score
  garden_id             
  37254     count      6
            mean      20
            std        0
            min       20
            25%       20
            50%       20
            75%       20
            max       20
  37273     count      1
            mean      17
            std      NaN
            min       17
            25%       17
            50%       17
            75%       17
            max       17
  37284     count      1
            mean      19
            std      NaN
            min       19
            25%       19
            50%       19
            75%       19
            max       19
  37288     count      1
            mean      11
            std      NaN
            min       11
            25%       11
            50%       11
                 ...
  </code></pre>
  
  <p>I was going to try modifying something like: <a href="https://stackoverflow.com/questions/19124148/modify-output-from-python-pandas-describe">modify-output-from-python-pandas-describe</a>, but I only get this:</p>
  
  <pre><code>Out[40]: 
  Empty DataFrame
  Columns: [score]
  Index: []
  </code></pre>
  
  <p>when I run <code>df.groupby('garden_id').describe().loc[['count']]</code></p>
  
  <p>I did try <code>newframe = df.groupby('garden_id').describe().count() &gt; 3</code>, but I get a mask showing which records are true and which false, so not really sure how to use this, either.</p>
  
  <p>Is there a way I can filter out desired records directly using the <code>describe</code> method without having to deal with data masking, etc.?</p>
