RE: st: RE: Creating / generating Industry level time dummy variables

["Ben Hoen" <bhoen@lbl.gov>]

I think the lname option of group specifies a name for the group variable value labels.  One still needs to break the categorical variable into its respective dummy variables for each level.  

Instead of the method I listed one could also use:

tab industrytimegroupvar, g(it) //using "it" as an abbreviation for industrytime.  This sill create a dummy for each level but will not store the value labels.

Here is more info:  http://www.stata.com/support/faqs/data-management/creating-dummy-variables/

Cheers,

Ben

Ben I think one could use lname in the main command it self to label
the dummies.

Please correct me if I am wrong.
