no room to add more observations
An attempt was made to increase the number of observations beyond what is
currently possible. You have the following alternatives:

1. Store your variables more efficiently; see help compress. (Think of
Stata's data area as the area of a rectangle; Stata can trade off
width and length.)

2. Drop some variables or observations; see help drop.

3. Increase the amount of memory allocated to the data area using the set
memory command; see help memory.
