. use "C:\AAA Miker Files\newer web pages\soc_meth_proj3\cps_y2k_numeric.dta", > clear 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. r(901);
