title: Lasso and Ridge estimator
body: <p>I have a txt file containing a large set of data. 
  How do I go about using the lasso or the ridge estimator to fit a regression equation?</p>
  
  <p>I got as far as using:
  gridge
  
  <p>However, I am unsure of what that lambda section is doing. I found it on a website and have no idea what values to put there.</p>
  
  <p>And I don't know how to interpret the output:
  modified HKB estimator is 5.465433
  modifiedL-W estimator is 7.6435664
  smallest value of GCV at 3.24</p>
  
  <p>How am I supposed to fit a regression equation using that information?</p>
