title: What does the CV stand for in sklearn.linear_model.LogisticRegressionCV?
body: <p>scikit-learn has two logistic regression functions:</p>
  
  <ul>
  <li>sklearn.linear_model.LogisticRegression</li>
  <li>sklearn.linear_model.LogisticRegressionCV</li>
  </ul>
  
  <p>I'm just curious what the CV stands for in the second one. The only acronym I know in ML that matches "CV" is cross-validation, but I'm guessing that's not it, since that would be achieved in scikit-learn with a wrapper function, not as part of the logistic regression function itself (I think).</p>
