You can extract the column names from e(b) using -indeplist- 
and you can use extended macro functions to manipulate the 
content. In particular with the -subinstr- you can replace 
ugly names with pretty names which may contain spaces as 
long as you remember to use compound quotes, see 
-help extended_fcn- and the example below. However if you 
want to use these names as column names than you should 
remember that spaces in column names are not well supported. 
You can use the underscore instead of a space and when 
displaying the matrix you can use -matlist- with the 
-underscore- option. This will replace the underscore with 
a space in the resulting table.

Hope this helps,
Maarten
