title: What does target mean in Scikit's Linear Regression object?
body: <p>I am using Scikit to perform ordinary linear regression on some random datapoints. However, I am confused as to what they mean by <code>target values</code> in their <a href="http://scikit-learn.org/dev/modules/generated/sklearn.linear_model.LinearRegression.html" rel="nofollow">documentation</a> of the fit method.</p>
  
  <p>I am setting <code>X</code> to be an array of datapoints of the shape 100 x 2 (two dimensional). What do I pass as input for the <code>y</code> argument?</p>
