title: how to group observations in stata
body: <p>I'm a beginner with stata so this question might be easy for some of you. 
  I have a Dataset with Firmspecific data. One variable is <code>Branche</code> which contains the following lines of business: <code>Consumer</code>, <code>Utilities</code>, <code>Food/Beverage</code>, <code>Technology</code>, <code>Logistics/Transportation</code>, <code>Retail</code>, <code>Insurance</code> etc.
  Now I want to form groups, for example the group <code>Consumer</code> which should contain <code>Retail, Food/Beverages, Consumer</code> but with the command generate <code>Consumer = Consumer Retail Food/Beverages</code> it doesn't work. Does anyone know what the right command would be? Thanks!</p>
