Hello Statalist scholars,

I am trying to generate a variable that will indicate missing BEFORE FIRST YEAR of OBSERVATION and missing AFTER FIRST YEAR of OBSERVATION.
Here is a sample of the data:

ID  Y1  Y2  Y3  Y4  Y5  Y6  Y7
1    .      .      x    x     x     x   x
2    .     x      .    x     x     x   x
3    .      .      x    x    .     x   x
4    .      x     .    x     x     .   x
5    x     x     .   x      x     x  .

Any advice is very much appreciated!  

Thank you so much for your time!
