HI statalist,

I'm trying to run a panel data regression where the dependent variable is a binary variable and I need to measure the effect of an independent variable which is time invariant.
Please consider the following:
Code:
 input HM Age gender income caste

            HM        Age     gender     income      caste
  1. 0 45 0 4000 0
  2. 1 23 1 2500 1
  3. 1 56 1 3000 1
  4. 1 38 1 3000 0
  5. 0 60 1 1000 1
  6. 1 65 0 5000 1
  7. 0 50 0 6000 1
  8. end

. list

     +------------------------------------+
     | HM   Age   gender   income   caste |
     |------------------------------------|
  1. |  0    45        0     4000       0 |
  2. |  1    23        1     2500       1 |
  3. |  1    56        1     3000       1 |
  4. |  1    38        1     3000       0 |
  5. |  0    60        1     1000       1 |
     |------------------------------------|
  6. |  1    65        0     5000       1 |
  7. |  0    50        0     6000       1 |
     +------------------------------------+
dependent variable is HM. I need to find effect of gender and caste on HM. But since gender and caste are time invariant I'm unable to figure out how to obtain the coefficient.
I'm struggling terribly with this regression and am completely lost. Any help would be greatly appreciated.
Thanks.
