title: How should I generate outliers randomly?
body: <p>I'm generating a random dataset. My dataset is sequential, and has upper and under limits. At some random points, I want my dataset to have outliers above and under limits. Here's my code.</p>
  
  <pre><code>generated_data = (12) * np.random.rand(100) + 630
  outlier_data = (12) * np.random.rand(20) + (*HERE'S THE PROBLEM)
  merged_data = np.concatenate((generated_data, outlier_data))
  </code></pre>
  
  <p>After this, I think I will shuffle the merged_data. But I don't know how to generate outliers properly.</p>
