I'm a very new user for stata and also the survival
analysis.. As i'm predicting bank failure that
contains some macro-economic data that is the same for
every banks but varies from time to time. However ,
after i used stcox regression, i encountered problems
as follows;
         - all statistics except coefficients
especially for macro variables (like rintsd variable
below)are all missing.
         - when i tried the different combination of
variables some macro variables showed statistics.
           t |
      censor |      Coef.   Std. Err.      z    P>|z|

Please could some of you suggest me how to solve this
problem and tell me what exactly the cause is?


Thank you in advance...
