RE: st: RE: Problem with generating time dummies in panel data

Thank you at least I get the year dummies, but again I am facing with a 
problem;
Namely, the variable minder is defined as hp<h and gets the value 1 if this 
is the case, gets value 0 if this is not the case for each year. Now when I 
list the variables I see value 0 is attached to a year even if there is no 
minder value associated with the year. For example
      +-----------------------------------------------------------+
      |      resp96      y   minder   minder1   minder2   minder3 |
      |-----------------------------------------------------------|
   1. |         701   1994        0         1         0         0 |
   2. |         701   1996        1         0         1         0 |
   3. |        1602   1994        .         1         0         0 |
   4. |        1602   1996        .         0         1         0 |
   5. |        1602   1998        .         0         0         1 |
      |-----------------------------------------------------------|

For resp96 1602, there is no minder variable present, but if you look at the 
dummies there are values attached to them.
If I use them in a regression, then I get muticollinearity and automatically 
dropped by stata.
My excuses for the inconvienient results but I am stucked with this problem 
by days.

Thank you in advance,
d
