title: When to use one-hot encoding and when to use dummy variable?
body: <p>I have short question here. I want to know when and what situation to use one-hot encoding and when should use dummy variable. </p>
  
  <p>I am planning to do clustering analysis with categorical and numerical variables. I read in one forum that I can try encode the categorical variables using one-hot encoding. But I wonder what makes it different with dummy variable.</p>
  
  <p>Thanks</p>
